A sensor can be mounted easily and an insulating distance between the sensor and a receiving blade can beheld reliably. A through-hole 7 is formed between plug insertion holes 6, 6, and a sensor 16 which detects a spark discharge occurring between plug blades is disposed internally of the through-hole 7. An insulating partition wall 13 is disposed between receiving blades 17, 17 in a standing manner, the sensor 16 is accommodated inside the partition wall, and arrangement is performed such that a portion of the sensor faces the through-hole. An outlet case is formed with an intermediate base body 5 provided with a mounting portion of the receiving blade 17 and a partition wall 13, a main body 3 which holds a circuit board 22 and the intermediate base body 5, and a cover body 4 which covers a front face of the main body 3.
A power source outlet device which is provided on a front face of an outlet case formed from insulating material with at least one pair of plug insertion holes, and receiving blades paired which pinch plug blades of a plug being disposed inside the plug insertion holes, and the power source outlet device having a through-hole between the plug insertion holes on the front face of the outlet case, and a sensor which detects a spark discharge occurring between the plug blades being disposed internally of the through-hole, characterized in that a partition wall made from insulator is disposed between the receiving blades in a standing manner, the sensor is received in the partition wall, and the sensor is disposed such that a portion thereof faces the through-hole.
A power source outlet device which is provided on a front face of an outlet case formed from insulating material with at least one pair of plug insertion holes, and receiving blades paired which pinch plug blades of a plug being disposed inside the plug insertion holes, and the power source outlet device having a through-hole between the plug insertion holes on the front face of the outlet case, and a sensor which detects a spark discharge occurring between the plug blades being disposed internally of the through-hole, characterized in that
