    摘要： A ceramic composition having a high dielectric constant which has good stability with temperature variation and the passage of time includes BaTiO3 in which the molecular ratio of Ba to Ti ranges from about 0.9 to 1.1 as the basic constituent and about 0.1 to 10 mol % of at least one compound selected from the group of Nb2O5 and Ta2O5 and about 0.01 to 15 mol % of at least one compound selected from the group consisting of In2O3, Ga2O3, Tl2O3, MgO, ZnO and NiO as sub constituents.
