MULTILAYER CERAMIC ELECTRONIC COMPONENT

To provide a compact multilayer ceramic electronic component capable of having high capacity.SOLUTION: A multilayer ceramic electronic component comprises: a laminated structure which includes a laminated portion having ceramic layers and internal electrode layers laminated alternately, which has a substantially rectangular parallelepiped shape, in which the plurality of laminated internal electrode layers are formed so as to be alternately exposed to two opposing end surfaces, and which has an upper surface and lower surface in a lamination direction and two side surfaces in addition to the two end surfaces; and side margins which are provided so as to cover end portions of the plurality of laminated internal electrode layers extending toward the two side surfaces, which contain a ceramic as a main component, and which have a thickness of 10-70 μm inclusive. In any of the internal electrode layers, with respect to a first straight line drawn from a tip on a side margin side in an opposing direction in which the two side surfaces oppose each other, a distance in the opposing direction between the tip and one position closer to the tip from either of a first position and a second position is 15 μm or less, wherein: in the first position, a thickness from a surface on one side in the thickness direction first reaches a local maximum value; and in a second position, a thickness from a surface on the other side first reaches a local maximum value.SELECTED DRAWING: Figure 5 【課題】 高容量を実現することができる小型の積層セラミック電子部品を提供する。【解決手段】 積層セラミック電子部品は、セラミックス層と内部電極層とが交互に積層された積層部分を含み、略直方体形状を有し、積層された複数の内部電極層が、対向する２端面に交互に露出するように形成され、２端面以外に積層方向の上面および下面と、２側面とを有する積層構造を備え、積層された複数の内部電極層が２側面に延びた端部を覆うように設けられ、セラミックスを主成分とし、１０μｍ以上７０μｍ以下の厚みを有するサイドマージンを備え、いずれかの内部電極層において、サイドマージン側の先端から２側面が対向する対向方向に引いた第１直線を基準として、厚み方向の一方側の表面までの厚みが最初に極大値となる第１位置と、他方側の表面までの厚みが最初に極大値となる第２位置と、のうち先端から近い方と先端との対向方向の距離が１５μｍ以下である。【選択図】 図５
