Abstract

PURPOSE:To improve adhesion between the upper and rear surfaces and an electrode layer of the main body of an element, by forming the upper and the rear surfaces of the main body of the element as coarse surfaces, and providing the electrode layer on the coarse surface. CONSTITUTION:A conductive polymer PTC resistor element comprises polymer and a conductive material, which is mixed into polymer in a dispersing mode, and has a positive resistive temperature characteristic. In this element 1, the upper and rear surfaces of a main body 2 of the element are formed as coarse surfaces 2b. An electrode layer 3 is formed on the coarse surface 2b. Therefore the junction strength at the contact interface between each wave shaped coarse surface 2b and the electrode layer 3 becomes very strong in the conductive polymer PTC resistor element 1. The very rigid electrode 3 is obtained against external force. Resistivity as the resistor element becomes small. Thus, the PTC resistor element 1, wherein the repeating characteristics are excellent and the excellent ohmic property can be sustained, is obtained.
