PROBLEM TO BE SOLVED: To provide a small-sized multilayer ceramic capacitor having a high capacity, and the manufacturing method of the capacitor which excels in the reliability comprising its capacity-temperature characteristic, its high-temperature-loaded life time, and the like, even when thinning its dielectric layers. SOLUTION: In each dielectric layer 5 of the multilayer ceramic capacitor, there coexist the barium titanate grains containing alkaline earth components at the rate not larger than 0.2 atom% (BMTL) wherefrom Ba is excluded, and the barium titanate grains containing alkaline earth components at the rate not smaller than 0.4 atom% (BMTH) wherefrom Ba is excluded, with each other at the organizing rate having an area ratio relation of BMTL/BMTH=0.1-9. Also, each dielectric layer 5 satisfies the relation of DL≤DH, when the mean grain sizes of BMTL and BMTH are represented respectively by DL and DH. Further, in a main body 1 of the multilayer ceramic capacitor, the dielectric layers 5 and inner-electrode layers 7 are laminated alternately. COPYRIGHT: (C)2006,JPO&NCIPI
