A laminated ceramic capacitor capable of achieving both a high dielectric constant and high electrical insulation property even when the thickness of the dielectric ceramic layer is less than 1 μm, contains a plurality of laminated dielectric ceramic layers and a plurality of internal electrodes at interfaces between the dielectric ceramic layers, where dielectric ceramic layers are made of dielectric ceramic containing a perovskite-type compound represented by ABO3 as a main ingredient, and R (R is La or the like), M (M is Mn or the like) and Si as accessory ingredients. When crystal grains of 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, the first crystal grains and the second crystal grains have a peak P1 and P2 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%.
