Abstract
A multilayer ceramic capacitor includes: a multilayer structure in which each of a plurality of ceramic dielectric layers and each of a plurality of internal electrode layers are alternately stacked wherein: a concentration of a rare earth element of at least one of an end margin region and a side margin region is lower than that of a capacity region; a total concentration of Si and B of the at least one of the end margin region and the side margin region is higher than that of the capacity region.
