Abstract

A multilayer ceramic capacitor includes: a ceramic multilayer structure having a structure in which each of ceramic dielectric layers and each of internal electrode layers are alternately stacked and are alternately exposed to two edge faces of the ceramic multilayer structure, a main phase of the plurality of ceramic dielectric layers having a perovskite structure that includes Ca and Zr and is expressed by a general formula ABO; and a pair of external electrodes that are formed on the two edge faces, wherein 300×TE/TA−12≤30 is satisfied when a volume TA is a length C×a width C×a thickness Cof the ceramic multilayer structure and a volume TE is a length E×a width E×a thickness E×a stacked number of the plurality of internal electrode layers in a capacity region.
