Disclosed is a dielectric ceramic composition having a high dielectric constant, which can be fired along with silver and silver alloys at temperatures not higher than 1000 DEG C. To a two-component dielectric ceramic composition comprising a solid solution that consists essentially of lead nickel niobate Pb(Ni+E,fra 1/3+EE Nb+E,fra 2/3+EE )O3 and lead titanate PbTiO3, added is at least one additive selected from the group consisting of the compounds Pb3O4, CuO and WO3 capable of forming a composition of a chemical formula Pb(Cu+E,fra 1/2+EE W+E,fra 1/2+EE )O3, and manganese oxide. The additives have the ability to promote the sintering of the two-component composition and to lower the firing temperature for the composition.
