Abstract

A multilayer ceramic capacitor includes: a multilayer chip in which each of dielectric layers and each of internal electrode layers are alternately stacked and are alternately exposed to two edge faces thereof; and external electrodes formed on the two edge faces; wherein: the external electrodes have a structure in which a plated layer is formed on a ground layer whose main component is a metal or an alloy, a thermal expansion coefficient of the metal being larger than that of a main ceramic component of the dielectric layer, the ground layer including a ceramic additive; outermost layers of the multilayer chip are cover layers whose main component is a main component of the dielectric layer; and thermal expansion coefficients satisfy a relationship of, the main component of the ground layer>the main component of the cover layers>the ceramic additive.
