Abstract
A laminated ceramic capacitor which has a dielectric ceramic with a high dielectric constant and has excellent reliability against changes in temperature and mechanical shocks, even when dielectric ceramic layers are reduced in thickness employs a dielectric ceramic containing (BaCa)TiO(where 0.045≦x≦0.15 and 0.98≦y≦1.05) as its main constituent and containing ReO(where Re is at least one of Gd, Dy, Ho, Yb, and Y), MgO, MnO, VO, and SiOas accessory constituents, which is represented by the general formula: 100(BaCa)TiO+aReO+bMgO+cMnO+dVO+eSiO, and satisfies each of the following conditions: 0.65≦a≦1.5; 0.98≦y≦1.05; 0.15≦b≦2.0; 0.4≦c≦1.5; 0.02≦d≦0.25; and 0.2≦e≦3.0.
