Abstract
A monolithic ceramic component has inner electrodes which are thin having a thickness of from about 0.2 .mu.m to 0.7 min, and thereby, delamination is inhibited even though ceramic layers are thin, having a thickness up to about 3 .mu.m. The mean particle size of the ceramic grains of the ceramic layers is up to 0.5 .mu.m, so that the concavities and convexities at the interfaces between the inner electrodes and the ceramic layers can be reduced. Preferably, metal powder in a paste used to form the inner electrodes has a mean particle size of from about 10 to 200 nm, and thereby, the metal filling ratio and the smoothness of the inner electrodes can be enhanced, and the coverage can be improved.
