Resistive element

Abstract

Abstract PURPOSE:To make the variation of the electric resistance value of a resistive element small and to improve a mass productivity by forming a high resistive layer between an outer electrode covering the end of a resistor and the resistor and by forming a film-like inner electrode of the materials which maintain an electrical conductivity in the resistor and the outer electrode respectively, in a predetermined area including the end face of the resistor. CONSTITUTION:An inner electrode 3 is obtained by drying and baking a silver- palladium alloy or paste-like material applied to a predetermined area of the end face 1A of a resistor 1, while an outer electrode 4 is obtained by dipping, drying and baking the paste-like material of a part including the end face of the inner electrode 2 and resistor 1 and the side face in the vicinity of the end face. Thus, the circumference of a copper alloy is placed in a reducing atmosphere, a high resistive layer is formed on the surface of a resistor 1 coming in contact with the copper alloy, and parts causing the inner electrode 3 to intervene are kept in continuity between the resistor 1 and inner electrode 3 and between the inner electrode 3 and outer electrode 4, respectively. Therefore, an electrode area is easy to control and the variation of a resistance value can be made small.
