ABSTRACT:
A multilayer ceramic capacitor1having internal electrode layers3, internal dielectric layers2having the thickness of less than 2 μm, and external dielectric layers20wherein; the internal dielectric layers2and the external dielectric layers20include a plural number of dielectric particles2a, 20a, and when y1is ratio(D50a/D50b) of D50aand D50bwhere D50ais an average particle size of dielectric particles2aincluded in the internal dielectric layers2and D50bis an average particle size of dielectric particles20aincluded in the external dielectric layer20and located at least 5 μm away from an internal electrode layer3a, arranged outermost part of all the internal electrode layers, to the stacked direction, and x is thickness of the internal dielectric layer2, y1and x satisfy the following equations, y1≦−0.75x+2.275 and y1≧−0.75x+1.675. According to the present invention, even when thickness of internal dielectric layers2were made thinner, a multilayer ceramic capacitor1wherein improvements in all kinds of electric characteristics, specially an improvement in TC bias characteristic while having sufficient dielectric constant can be expected.
