Abstract
A multilayer ceramic capacitor includes: a multilayer structure in which dielectric layers and internal electrode layers are alternately stacked and are alternately exposed to two edge faces of the multilayer structure; and a first cover layer and a second cover layer that sandwich the multilayer structure, a main component of the first cover layer and the second cover layer being the same as that of the dielectric layers, wherein the first cover layer is thicker than the second cover layer, wherein a concentration of Mn of at least a part of the first cover layer is higher than a concentration of Mn of the dielectric layers in an effective capacity region in which a set of internal electrode layers exposed to a first edge face of the multilayer structure face with another set of internal electrode layers exposed to a second edge face of the multilayer structure.
