To provide multilayer ceramic electronic components that are each able to suppress electric field concentration.SOLUTION: There is provided a multilayer ceramic electronic component including: a multilayer body 10 having a plurality of stacked ceramic layers 20, and a plurality of internal conductive layers 30 stacked on the ceramic layers 20; and external electrodes 40 each connected to the internal conductive layers 30. In each of the internal conductive layers 30, there exist holes each having different area equivalent diameters. The plurality of holes have first holes in which ceramic pillars connecting a one side ceramic layer 20 and the other side ceramic layer 20 in the internal conductive layers 30 are disposed inside, and second holes in which ceramic pillars are not disposed inside. When an area equivalent diameter in which a cumulative value in a cumulative distribution of area equivalent diameters of the holes existing in each of the internal conductive layers 30 is 90% is defined as an area equivalent diameter D90, an abundance ratio of the first holes in a first population including holes each having the area equivalent diameter D90 or more is 14% or more.SELECTED DRAWING: Figure 4A 【課題】電界集中を抑制することが可能な積層セラミック電子部品を提供すること。【解決手段】積層セラミック電子部品であって、積層された複数のセラミック層２０と、前記セラミック層２０上に積層された複数の内部導体層３０とを有する積層体１０と、内部導体層３０に接続される外部電極４０と、を備え、内部導体層３０には、面積相当径の異なる複数の穴が存在し、複数の穴は、内部導体層３０の一方側のセラミック層２０と他方側のセラミック層２０とを接続するセラミック柱が内部に配置された第１の穴と、セラミック柱が内部に配置されていない第２の穴と、を有し、内部導体層３０に存在する複数の穴の面積相当径の累積分布における累積値が９０％となる面積相当径を面積相当径Ｄ９０としたとき、面積相当径が面積相当径Ｄ９０以上の穴によって構成される第１の母集団における第１の穴の存在比率は、１４％以上である。【選択図】図４Ａ
