Keramischer Kondensator und seine Herstellungsmethode.

摘要

Disclosed is a ceramic capacitor of a monolayer structure or a multi-layer structure, which has characteristic X7R (characteristic B) and which is high in reliability in direct current breakdown voltage at 125 DEG C and small in size. The ceramic capacitor has a dielectric layer (12) and internal electrodes (14) disposed so as to interpose the dielectric layer. The dielectric layer (12) is composed of a sintered body of ceramic particles whose core sections are made mainly of BaTiO3 and whose shell sections are made from BaTiO3 in the form of a solid solution composed of an oxide of one or more than one element selected from Mg, Ca, Sr and Zn and an oxide of one or more than one element selected from Sc, Y, Gd, Dy, Ho, Er, Yb, Tb, Tm and Lu.
