Abstract

A multilayer ceramic capacitor includes a ceramic multilayer body including dielectric layers and inner electrodes stacked on top of one another with the dielectric layers interposed between a corresponding pair of the inner electrodes. The dielectric layers each include a perovskite-type compound including Ba and Ti. A boundary layer including Mg and Mn is located at an interface between an outermost inner electrode and an outermost dielectric layer. The outermost inner electrode is located at an outermost position of the inner electrodes in a direction in which the inner electrodes are stacked. The outermost dielectric layer is located outside the outermost inner electrode. A proportion in which the boundary layer is present at the interface is about 69% or more. A continuity of the outermost inner electrode is about 60% or more.
