Abstract:
1. A multilayer ceramic capacitor, comprising: (i) dielectric layers containing dielectric ceramics containing crystal grains containing barium titanate as the main ingredients and containing magnesium, vanadium, manganese, terbium, and at least one rare earth element (RE) selected from yttrium, dysprosium, holmium, and erbium; and (ii) internal electrode layers, the dielectric layers and the internal electrode layers being alternately laminated, the dielectric ceramics containing, with respect to 100 mol of titanium constituting the barium titanate, 0.02 to 0.2 mol of vanadium in terms of V in the X ray diffraction chart of the dielectric ceramics, the diffraction intensity at an angle of the diffraction peak of the (200) plane showing a cubic barium titanate being larger than the diffraction intensity at an angle of the diffraction peak of the (002) plane showing a tetragonal barium titanate and the curie temperature being 110 to 120° C.
