Abstract
A multilayer ceramic capacitor includes a multilayer body that includes an inner layer portion including a plurality of inner dielectric layers and a plurality of inner electrode layers laminated in a first direction, and a pair of outer layer portions holding the inner layer portion therebetween in the first direction, and a pair of outer electrodes located at two end portions of the multilayer body in a second direction and connected to the inner electrode layers. The plurality of inner electrode layers include Ni as a main component, and an Mn—Ni oxide area is included in at least a portion of any of the plurality of inner electrode layers.
