ABSTRACT:
This invention provides an electrode on a heat-resisting and isolating substrate which is low-priced and has a stable character and the manufacturing process therefor. A paste which comprises 0.05 to 40 weight % of a metal material containing silver component of 0.5 to 100 weight % and the remaining weight % of an organic vehicle, is formed on the substrate, and is heated at temperatures of 250.degree. to 900.degree. C. and consequently a metallic particle layer of 0.05 to 2 microns in thickness is formed on the substrate, and then an electrode of nickel and copper of 0.1 to 20 microns in thickness is built up on it by electroless plating.
