Abstract:
A multilayer ceramic capacitor that includes a laminate having a plurality of dielectric layers and a plurality of internal electrodes that are alternately stacked, and external electrodes. Each of the dielectric layers contains first crystal grains and second crystal grains that each contain Ba, Ti, and a rare-earth element. A first mole ratio M1 of the rare-earth element to the Ti in a range from an interface to 50 nm inclusive of the first crystal grains and a second mole ratio M2 of the rare-earth element to the Ti in a range of 50 nm to 100 nm inclusive from the interface satisfy 0.95≤M1/M2≤1.05. A third mole ratio M3 of the rare-earth element to the Ti in the second crystal grains is half or less of a fourth mole ratio M4 of the rare-earth element to the Ti in the first crystal grains.
