Abstract
A multilayer ceramic capacitor includes a ceramic body, and external electrodes on opposite side surfaces of the ceramic body. The ceramic body includes an inner layer portion including a plurality of ceramic layers, and first and second internal electrodes each arranged at interfaces between the ceramic layers defining the inner layer portion, and also includes outer layer portions arranged on an upper surface and a lower surface of the inner layer portion. The ceramic layers defining the inner layer portion include as a main component a perovskite-type compound containing Ba and Ti. The amount of Mg contained in the ceramic layers defining the inner layer portion preferably is 0 to about 0.4 part by mole per 100 parts by mole of Ti, for example. The thickness of the ceramic layers defining the inner layer portion preferably is not more than about 0.55 μm, for example.
