Barium titanate (BaTiO 3 ) and barium zirconate (BaZrO 3 ) are made into a solid solution at a predetermined ratio. Specifically, a dielectric ceramic composition is represented by a basic composition (BaTiO 3 ) (1-X) (BaZrO 3 ) X (in the formula, X satisfies 0.70≦X≦0.95). More preferably, X satisfies 0.73≦X≦0.90 in this range. Such a dielectric ceramic composition may be integrated with alumina to form a composite ceramic structure. |
