Abstract
The dielectric ceramic composition is composed of a sintered body of ceramic particles containing Ba.sub.2 Ti.sub.5 O.sub.11 as a major component. The ceramic particles may contain Ag in the form of solid solution at the rate of 0.2% to 3.0% by mole. the ceramic particles may further contain Ba.sub.2 TiSi.sub.2 O.sub.8 so the BaTi.sub.5 O.sub.11 /Ba.sub.2 TiSi.sub.2 O.sub.8 ratio is 1.5 to 9 BaTi.sub.5 O.sub.11 to 1 Ba.sub.2 TiSi.sub.2 O.sub.8. The dielectric ceramic composition can be sintered at a low enough temperature to enable a highly conductive metal such as Ag, Cu or the like to be burned and sintered integrally.
