Abstract
A dielectric ceramic which is suitable for use in a laminated ceramic capacitor under a high-temperature environment, such as encountered in, for example, automobile use has a composition represented by the composition formula: (1−x) (BaCa)TiO+xCaTiO+aReO+bMgO+cMnO+dVO+eSiOin which Re is Gd, Dy, Y, Ho, and/or Er), 0.001≦x≦0.02, 0.08≦y≦0.20, 0.99≦m≦1.05, 0.01≦a≦0.04, 0.005≦b≦0.035, 0≦c≦0.01, 0≦d≦0.01, 0.01≦e≦0.04 when a, b, c, d, and e are each expressed in terms of parts by mol with respect to 1 mol of (1−x) (Ba,Ca)TiO+xCaTiO. This dielectric ceramic can constitute the dielectric ceramic layers of a laminated ceramic capacitor.
