Abstract
A laminated ceramic capacitor is provided which is excellent in reliability even when its dielectric ceramic layers thinned. For a dielectric ceramic in a laminated ceramic capacitor, a ceramic is used which includes a main component containing a barium titanate based composite oxide represented by the general formula: (BaCaSrRe)(TiZrM)O, where Re is La or the like, M is Mg or the like, and the respective relationships of 0.05≦x≦0.50, 0.02≦y≦0.3, 0.85≦k≦1.05, 0≦h≦0.25, 0≦m≦0.50, and 0≦n≦0.40 are satisfied; and an accessory component as a sintering aid, wherein the average grain diameter of crystal grains in a sintered body is 0.6 μm or less.
