Multilayer ceramic electronic device and method of manufacturing the same

Abstract

A multilayer ceramic electronic device includes an element body including a dielectric layer and an internal electrode layer. The dielectric layer and the internal electrode layer are laminated. The dielectric layer includes dielectric grains containing a main component represented by a formula A1B1O3, where A1 includes Ba and at least one selected from the group consisting of Ca and Sr or includes only Ba, and B1 includes Ti and Zr or includes only Ti. The dielectric grains include electrode-contacting grains in contact with the internal electrode layer and porous grains having a pore in a section parallel to a lamination direction. A number ratio of the dielectric grains that fall under both the electrode-contacting grains and the porous grains to the electrode-contacting grains is 0.1% or more and 15.0% or less.
