A multilayer ceramic capacitor 1 having internal electrode layers 3, internal dielectric layers 2 having the thickness of less than 2 m, and external dielectric layers 20 wherein; the internal dielectric layers 2 and the external dielectric layers 20 include a plural number of dielectric particles 2a, 20a, and when y1 is ratio(D50a/D50b) of D50a and D50b where D50a is an average particle size of dielectric particles 2a included in the internal dielectric layers 2 and D50b is an average particle size of dielectric particles 20a included in the external dielectric layer 20 and located at least 5 m away from an internal electrode layer 3a, arranged outermost part of all the internal electrode layers, to the stacked direction, and x is thickness of the internal dielectric layer 2, y1 and 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 layers 2 were made thinner, a multilayer ceramic capacitor 1 wherein improvements in all kinds of electric characteristics, specially an improvement in TC bias characteristic while having sufficient dielectric constant can be expected.
