PURPOSE:To obtain a relatively large CR product even if thickness of an dielectric ceramic layer is thin by adding ZnO, BaZrO3 to the basic component made of the specified composition of BaTiO3, NbO2.5+CoO. CONSTITUTION:The dielectric ceramic composition includes the basic component at 100 parts by weight showed with a composition formula alphaBaTiO3+betaNbO2.5+gammaCoO, ZnO at 0.01-0.20 parts by weight, and BaZrO3 at 0.10-2.00 parts by weight. In the formula, alpha, beta, gamma means values for satisfying 0.950<=alpha<=0.990, 0.006<=beta<=0.042, 0.002<=gamma<=0.020, alpha+beta+gamma=1. A capacitor is thereby made compact. |
