Claim Text:
1. A multilayer ceramic capacitor having a structure of internal electrode layers constituted by mutually bonded metal grains of various sizes being laminated alternately with dielectric layers constituted by mutually bonded ceramic grains of various sizes, wherein the ceramic grains constituting each dielectric layer include coarse ceramic grains whose coarse grain size Dcoa meets a condition “Tmin≦Dcoa≦Tmax” where Tmax represents a maximum thickness of the dielectric layer and Tmin represents a minimum thickness of the dielectric layer and a condition “Tabe≦Dcoa” where Tabe represents an average thickness of the dielectric layer, wherein a percentage of the coarse ceramic grains included in the ceramic grains constituting the dielectric layer is inside a range of 25 to 50 percent by volume, wherein an average grain size Dabe of the ceramic grains constituting the dielectric layer meets a condition “0.15×Tabe≦Dabe≦0.3 ×Tabe”.
