Abstract:
1. A laminated ceramic capacitor comprising: a plurality of laminated dielectric ceramic layers; and a pair of internal electrodes between different adjacent interfaces between the dielectric ceramic layers, wherein the dielectric ceramic layers comprise a dielectric ceramic containing a perovskite-type compound represented by ABO wherein when the crystal grains contained in the dielectric ceramic are classified into first crystal grains having grain sizes larger than one-fourth of the thickness of the dielectric ceramic layer and second crystal grains having grain sizes not larger than one-fourth of the thickness of the dielectric ceramic layer, each of the first crystal grains and the second crystal grains have a peak of grain size distribution, and the areal percentage of the first crystal grains on a cross section of the dielectric ceramic layer is 41 to 69%.
