Abstract: A ceramic capacitor comprising a dielectric ceramic element made of materials a metal oxide as the principal ingredient. On the surface of the dielectric ceramic element are formed a plurality of electrodes. The materials used for the electrode are selected such that their principal ingredients have a stronger oxidizing tendency than those used for the dielectric ceramic element. The electrode is formed by applying this electrode material on the surface of the dielectric ceramic element and subsequently baking in a non-reducing atmosphere. This process reduces the surface of the dielectric ceramic element underneath the electrode and a reduced layer is thus formed.

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.

Abstract: A manufacturing method for a ceramic capacitor superior in breakdown voltage ability, comprising a process of baking opposite electrode on the surface of ceramic dielectric composed mainly of metal oxide and that, simultaneous with or after the above process, of baking in a ring-like shape insulating layers for air cutoff on at least the edges of an electrode.
