Abstract:
1. A multilayer ceramic electronic component, comprising: a ceramic body including a plurality of dielectric layers and a recess portion formed in a length direction of at least one main surface thereof so as to be inwardly concave and satisfying T/W>1.0 when a width thereof is defined as W and a thickness thereof is defined as T; a plurality of first and second internal electrodes disposed in the ceramic body so as to face each other, having the dielectric layer interposed therebetween, and alternately exposed through both end surfaces of the ceramic body; and first and second external electrodes extended from the end surfaces of the ceramic body to the at least one main surface in which the recess portion is formed, and electrically connected to the first and second internal electrodes, respectively, wherein when the ceramic body is divided into an upper region At, corresponding to 70% to 90% of an overall thickness of the ceramic body, and a lower region Ab, corresponding to 10% to 30% of the overall thickness of the ceramic body, a ratio of an average particle size of Ab materials to an average particle size of At materials is less than 0.5.
