A multilayer ceramic capacitor comprising an internal electrode layer, an internal dielectric layer having a thickness of less than 2 mum, and an external dielectric layer is provided, wherein the internal dielectric layer and external dielectric layer contain a plurality of dielectric particles, and when assuming that an average particle diameter of the entire dielectric particles in the internal dielectric layer is D50a (unit: mum), an average particle diameter of the entire dielectric particles existing at a position being away at least by 5 mum from the outermost internal electrode layer in the thickness direction is D50b (unit: mum), a ratio (D50a/D50b) of the D50a and D50b is y (no unit), standard deviation of a particle size distribution of the entire dielectric particles in the internal dielectric layer is sigma (no unit), and a ratio that dielectric particles (coarse particles) having an average particle diameter of 2.25 times of the D50a exist in the entire dielectric particles is p (unit: %), the y and x satisfy a relationship of y<-0.75x+2.015 and y>-0.75x+1.740, the sigma satisfies sigma<0.091 and the p satisfies p<2.85%; by which a TC bias characteristic can be expected to be improved while maintaining various electric characteristics, particularly a sufficient permittivity, even when the internal dielectric layer is made thin.
