Abstract:
A multilayer ceramic capacitor includes: a multilayer structure in which each of a plurality of dielectric layers and each of a plurality of internal electrode layers are alternately stacked, the plurality of internal electrode layers being alternately exposed to a first edge face and a second edge face of the multilayer structure, wherein: a concentration of Mo with respect to a main component ceramic of an end margin region and a side margin region is lower than a concentration of Mo with respect to a main component ceramic of the dielectric layers in the multilayer structure.
