Abstract:
A dielectric ceramic composition that contains, as its main constituent, (Ba1-x-yCaxSry)(Ti1-z-wZrzHfw)O3 (in the formula, 0≦x+y≦0.2, 0≦z+w≦0.1), and contains CuO and Bi2O3, and the dielectric ceramic composition has a feature that the total content of the CuO and Bi2O3 is 10 parts by weight or more with respect to 100 parts by weight of the main constituent, and the molar ratio CuO/(CuO+Bi2O3) is 0.5 or less.
