Abstract

A multilayer ceramic capacitor includes a laminate including a plurality of dielectric layers laminated one on the other, the laminate being in a cuboid or substantially cuboid shape. The multilayer ceramic capacitor includes external electrodes on the end surfaces of the laminate. A first inner electrode layer exposed through the first end surface and a second inner electrode layer exposed through the second end surface are provided on the dielectric layer. A first region and a second region are defined in the first inner electrode layer and the second inner electrode layer, in which coverages of the first inner electrode layer and the second inner electrode layer to the dielectric layer are greater in the first region than in the second region.
