The main unit has a first guidance surface that indicates how to attach of the first pad and the second pad. The first guidance surface has a first marker in the first color at a position corresponding to an attachment position of the first pad and a second marker in the second color at a position corresponding to an attachment position of the second pad. ## Claims ### Claim 1 An automated external defibrillator comprising: a first pad at least partially colored in a first color; a second pad at least partially colored in a second color; and a main unit to which the first pad and the second pad are connected, the main unit comprising a first guidance surface indicating how to attach the first pad and the second pad, wherein the first guidance surface comprises a first marker comprising an first indicator capable of being turned on and/or blinked in the first color at a position corresponding to an attachment position of the first pad and a second marker comprising a second indicator capable of being turned on and/or blinked in the second color at a position corresponding to an attachment position of the second pad. ### Claim 2 (depends on 1) The automated external defibrillator according to claim 1, wherein lighting, blinking and turning off of the first indicator and the second indicator are switched in accordance with whether a difference between impedance values of the first pad and the second pad is smaller than or equal to a certain value. ### Claim 3 (depends on 1) The automated external defibrillator according to claim 1, wherein lighting, blinking and turning off of the first indicator are switched in accordance with a condition of attachment of the first pad to a patient. ### Claim 4 (depends on 3) The automated external defibrillator according to claim 3, wherein the first indicator is lit when a power of the automated external defibrillator is turned on, and is turned off when the first pad is correctly attached to the patient. ### Claim 5 (depends on 1) The automated external defibrillator according to claim 1, wherein lighting, blinking and turning off of the second indicator are switched in accordance with a condition of attachment of the second pad to a patient. ### Claim 6 (depends on 5) The automated external defibrillator according to claim 5, wherein the second indicator is lit when a power of the automated external defibrillator is turned on, and is turned off when the second pad is correctly attached to the patient. ### Claim 7 (depends on 1) The automated external defibrillator according to claim 1, wherein lighting, blinking and turning off of the first indicator and the second indicator are switched in accordance with whether both of the first pad and the second pad are correctly attached to a patient. ### Claim 8 (depends on 1) The automated external defibrillator according to claim 1, wherein a back surface, opposite to a surface that contacts a patient, of the first pad is colored in the first color and a back surface, opposite to a surface that contacts the patient, of the second pad is colored in the second color. ### Claim 9 (depends on 1) The automated external defibrillator according to claim 1, wherein the main unit further comprises a second guidance surface indicating how to attach the first pad and the second pad to a child, and wherein the second guidance surface comprises a third marker colored in the first color at a position corresponding to an attachment position of the first pad and a fourth marker colored in the second color at a position corresponding to an attachment position of the second pad. ### Claim 10 (depends on 9) The automated external defibrillator according to claim 9, wherein the third marker comprises a third indicator capable of being lit or blinked, and wherein one of the first indicator and the third indicator is lit, blinked, or turned off in accordance with a condition of attachment of the first pad to a patient and based on an input from an adult/child switching interface. ### Claim 11 (depends on 1) The automated external defibrillator according to claim 1, further comprising: an impedance measuring section which is configured to detect attachment of the first pad to a patient from an impedance value between the first pad and a body surface of the patient, wherein lighting, blinking and turning off of the first indicator are controlled so as to be different from each other depending on cases that are a first case where the first pad is not attached to the patient, a second case where the first pad is attached to the patient and the impedance value is normal, and a third case where the first pad is attached to the patient and the impedance value is abnormal. ### Claim 12 (depends on 11) The automated external defibrillator according to claim 11, wherein the impedance measuring section is configured to detect attachment of the second pad to the patient from an impedance value between the second pad and the body surface of the patient, and wherein lighting, blinking and turning off of the second indicator are controlled so as to be different from each other depending on cases that are a fourth case where the second pad is not attached to the patient, a fifth case where the second pad is attached to the patient and the impedance value is normal, and a sixth case where the second pad is attached to the patient and the impedance value is abnormal. ### Claim 13 An automated external defibrillator comprising: a main unit to which a first pad and a second pad are connectable, the main unit comprising a first guidance surface indicating how to attach the first pad at least partially colored in a first color and the second pad at least partially colored in a second color, wherein the first guidance surface comprises a first indicator capable of being turned on and/or blinked in the first color at a position corresponding to an attachment position of the first pad and a second indicator capable of being turned on and/or blinked in the second color at a position corresponding to an attachment position of the second pad. ### Claim 14 (depends on 13) The automated external defibrillator according to claim 13, further comprising: an impedance measuring section which is configured to detect attachment of the first pad to a patient from an impedance value between the first pad and a body surface of the patient, wherein lighting, blinking and turning off of the first indicator are controlled so as to be different from each other depending on cases that are a first case where the first pad is not attached to the patient, a second case where the first pad is attached to the patient and the impedance value is normal, and a third case where the first pad is attached to the patient and the impedance value is abnormal. ### Claim 15 (depends on 14) The automated external defibrillator according to claim 14, wherein the impedance measuring section is configured to detect attachment of the second pad to the patient from an impedance value between the second pad and the body surface of the patient, and wherein lighting, blinking and turning off of the second indicator are controlled so as to be different from each other depending on cases that are a fourth case where the second pad is not attached to the patient, a fifth case where the second pad is attached to the patient and the impedance value is normal, and a sixth case where the second pad is attached to the patient and the impedance value is abnormal.
