A multilayer ceramic capacitor of the present invention includes dielectric layers and each of the dielectric layers has a main component containing barium titanate, a first auxiliary component composed of at least one kind selected from the group consisting of MgO, CaO, BaO, and SrO, a second auxiliary component containing a silicon oxide as a main component, a third auxiliary component composed of at least one kind selected from the group consisting of V2O5, MoO3, and WO3, a fourth auxiliary component composed of an oxide of at least one kind of first rare-earth element (R1) selected from the group consisting of Sc, Er, Tm, Yb, and Lu, and a fifth auxiliary component composed of CaZrO3 or a mixture (CaO+ZrO2) of CaO and ZrO2. Zr diffuses in crystal grains forming the dielectric layers and, in the crystal grains each having an average grain diameter, the depth of a diffusion layer of Zr is 10 to 35% relative to the diameter of the crystal grain. Therefore, the multilayer ceramic capacitor is excellent in reliability wherein the capacitance-temperature characteristic, i.e. a time-dependent change in capacitance, satisfies the EIA standard X8R characteristic (ΔC/C=±15% at −55 to +150° C.) and the resistance change ratio in an acceleration test is small (average life is long).
