Abstract
A multilayer ceramic capacitor has a laminate including dielectric layers laminated alternately with internal electrode layers of different polarities, wherein the dielectric layer contains ceramic grains having Ba, Ti, and X (wherein X represents at least one type of element selected from the group consisting of Mo, Ta, Nb, and W) and a variation in the concentration distribution of X above in the ceramic grain is within ±5%. The multilayer ceramic capacitor can offer excellent service life characteristics even when the thickness of the dielectric layer is 0.8 μm or less, as well as excellent bias characteristics.
