The present invention provides a multilayer ceramic capacitor which ensures high dielectric constant and good temperature characteristics and further improves IR temperature dependency.n n n According to the present invention, there is provided a multilayer ceramic capacitor (1) having a dielectric layer (2) composed of a dielectric ceramic composition and a capacitor element body (10) in which internal electrode layers (3) are alternately stacked. Comprising a plurality of crystal grains (2a), Ca diffusion region 25a in which at least the Ca is diffused inward from the surface of the crystal grains is formed in the crystal grains (2a), the average particle diameter (D50) In the case where the crystal grains 2a exhibiting a value are targeted, the dielectric porcelain composition in which the average depth T of the Ca diffusion region 25a is controlled in the range of 10 to 30% of the D50 can be provided. . |
