Abstract:
A laminated ceramic capacitor which has a long high temperature load life, small variations in life, large capacitance, high electrical insulation property, and favorable capacitance temperature characteristics, even when high strength electric field is applied while reducing the thickness of dielectric ceramic layers uses a dielectric ceramic represented by the formula: 100(Ba1-xCax)mTiO3+aMgO+bVO5/2+cReO3/2+dMnO+eSiO2 where Re being at least one of Y, La, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb), 0.05≦x≦0.15, 0.01≦a≦0.1, 0.05≦b≦0.5, 1.0≦c≦5.0, 0.1≦d≦1.0, 0.5≦e≦2.5, and 0.990≦m≦1.030.
