Abstract:
1. A laminated ceramic capacitor comprising an inner layer section having dielectric ceramic layers and internal electrodes alternately stacked; and an outer layer section having dielectric ceramic layers without internal electrodes, the outer layer section disposed outside the inner layer section, wherein the dielectric ceramic layers constituting the inner layer and outer layer sections comprise a perovskite-type compound containing Ca and Zr; and Si and Mn, an average grain size of the dielectric ceramic constituting the outer layer section smaller than an average grain size of the dielectric ceramic constituting the inner layer section, and a Si/Mn molar ratio in the dielectric ceramic near interfaces between the internal electrodes and the dielectric ceramic layers of ≦15, the Si/Mn molar ratio is 0.1 to 13, the difference between the average grain size of the dielectric ceramic constituting the outer and inner layer section is at least 0.1 μm, and the dielectric ceramic is of the formula (Ca
