ABSTRACT:
A high-voltage ceramic capacitor comprises a dielectric ceramic element. Electrodes using silver material are formed on the opposite surfaces of the dielectric ceramic element. A reduced region is formed in the vicinity of the end-edge part of each of the electrodes on the surface of the dielectric ceramic element. This reduced region is formed by coating a reducing agent the main component of which is a material having a strong oxidizing inclination on the dielectric ceramic element and heating it. Furthermore, an external terminal is soldered to each of the electrodes.
