Abstract
An electrode for a PTC thermistor of the present invention includes a base layer having electrical conductivity and a sintered layer formed on the base layer. The sintered layer is formed by sintering a conductive powder and has electrical conductivity, and has roughness on a surface thereof. Thus, the present invention can provide an electrode for a PTC thermistor that has a large adhesion to the conductive polymer and can be produced easily.
