In a multilayer ceramic capacitor including: a laminated body layer formed by alternately laminating dielectric layers made of ceramic particles and internal electrodes; and a pair of external electrodes provided on at least both end surfaces of the laminated body layer and alternately connected to the internal electrodes electrically, the number of boundaries between ceramic particles per unit length of the dielectric layer in the lamination direction is larger than that in the direction connecting the pair of external electrodes. Thus increasing the number of ceramic grain boundaries between internal electrodes improves the insulation characteristic. Particularly, even if the number of ceramic particles thicknesswise decreases due to lamellation, increasing the number of grain boundaries suppresses deterioration of the insulation characteristic.
