Abstract
A multilayer ceramic capacitor includes a ceramic multilayer body including dielectric ceramic layers and inner electrodes laminated with the dielectric ceramic layers interposed therebetween, wherein the dielectric ceramic layers include a perovskite compound containing Ba and Ti, and the inner electrodes (a) contain Ni as a main component, (b) include segregation with the perovskite compound containing Ba and Ti, which is scattered in the inner electrodes and embedded in the inner electrodes, in amount equal to or higher than about 2%, and (c) include columnar segregation with the perovskite compound containing Ba and Ti, which penetrates through the inner electrodes from one main surface side to the other main surface side, in an amount equal to or lower than about 5%, or do not include the columnar segregation. Further, an average thickness of the inner electrodes is equal to or smaller than about 0.4 μm.
