Abstract
A monolithic ceramic capacitor comprises a dielectric ceramic element assembly, metal electrodes for external connection and conductive metal oxide layers formed between the ceramic element assembly and the metal electrodes for preventing reduction of metal oxide forming the dielectric ceramic material.
Claims12
A ceramic capacitor formed by a laminated dielectric ceramic element assembly comprising:
- a dielectric ceramic member consisting of a plurality of layers of metal oxide, respective said layers being not more than 50 .mu.m in thickness;
- and
- a plurality of layers of inner metal electrodes laminated with each other through said dielectric ceramic member to form electrostatic capacity,
- metal electrodes for external connection being formed on said dielectric ceramic element assembly to be connected with prescribed ones of said inner metal electrodes for obtaining electrostatic capacity,
- conductive metal oxide layers being formed between said dielectric ceramic element assembly and said metal electrodes for external connection for preventing reduction of said metal oxide forming said dielectric ceramic member.
