SEMICONDUCTOR CERAMIC AND A MULTILAYER SEMICONDUCTOR CERAMIC CAPACITOR

摘要

A purpose of the present invention is to provide a multilayer semiconductor ceramic capacitor, which makes coexistence of a high dielectric property and a high insulating resistance of a semiconductor ceramic possible by improving insulating property of the semiconductor ceramic component. In order to achieve such object, BaTiO3 based semiconductor ceramic of the invention is expressed by BaA(Ti1-α-&bgr;GaαNb&bgr;)BO3, wherein A/B mole ratio is within a range of 0.900 or more to 1.060 or less and α/&bgr; mole ratio is within a range of 0.92 or more to 100 or less.
