Resistor and method for manufacturing the same

A method for manufacturing a resistor, comprising:

• using a carrier to carry a resistance layer, wherein the resistance layer has a first surface and a second surface that are opposite to each other, and a first end surface and a second end surface that are opposite to each other, and the first surface is adhered to the carrier, and wherein each of the first surface and the second surface comprises a central portion, and a first end portion and a second end portion respectively located on two opposite sides of the central portion;
• removing portions of the resistance layer to form a first concave and a second concave in the first end portion and the second end portion of the second surface respectively;
• forming a first internal electrode and a second internal electrode in the first concave and the second concave respectively;
• removing the carrier;
• forming a first insulating protection layer and a second insulating protection layer on the central portion of the first surface and the central portion of the second surface respectively, wherein a length of the first insulating protection layer is greater than a length of the second insulating protection layer;
• forming a first thermal conductive layer and a second thermal conductive layer, wherein the first thermal conductive layer and the second thermal conductive layer respectively extend from the first end portion and the second end portion of the first surface to the first insulating protection layer and are separated from each other;
• and
• forming a first external electrode and a second external electrode, wherein the first external electrode extends from the first thermal conductive layer through the first end surface to the first internal electrode, and the second external electrode extends from the second thermal conductive layer through the second end surface to the second internal electrode.
