Abstract

Provided in a dielectric ceramic having flat capacitance characteristics and a high dielectric constant, and a multilayer ceramic electronic component (such as a multilayer ceramic capacitor) in which the dielectric ceramic is used. A multilayer ceramic capacitor includes a multilayer body having a plurality of dielectric ceramic layers and a plurality of internal electrodes, and external electrodes formed on the multilayer body. The composition of the multilayer body includes any of a bismuth layered compound containing Sr, Bi and Ti, a bismuth layered compound containing Sr, Bi and Nb, and a bismuth layered compound containing Ca, Bi and Ti as a primary ingredient, Bi and at least one of Cu, Ba, Zn and Li, and satisfies the conditions that if the Ti content is 400 molar parts or the Nb content is 200 molar parts, then (Bi content-Ti content) or (Bi content-Nb content) is equal to or greater than 1 molar part and less than 7.5 molar parts and the total content of Cu, Ba, Zn and Li is equal to or greater than 1 molar part and less than 10 molar parts.
