Zusammenfassung:	To improve the reliability of a ceramic electronic component.SOLUTION: A ceramic electronic component has a laminated structure in which a plurality of dielectric layers containing Ba and Ti and a plurality of internal electrode layers containing Ni and Sn are alternately laminated, and in at least one internal electrode layer of the plurality of internal electrode layers, a discontinuous portion is formed in a cross section including the stacking direction of the laminated structure, and in the surface exposed to the discontinuous portion, a high Sn concentration portion having a Sn concentration higher than an average Sn concentration of the one internal electrode layer is formed.SELECTED DRAWING: Figure 5 【課題】セラミック電子部品の信頼性を向上させること。【解決手段】セラミック電子部品は、ＢａおよびＴｉを含む複数の誘電体層と、ＮｉおよびＳｎを含む複数の内部電極層と、が交互に積層された積層構造を備え、前記複数の内部電極層の少なくともいずれか１層の内部電極層において、前記積層構造の積層方向を含む断面において途切れる不連続部が形成されており、前記不連続部に対して露出する表面に、Ｓｎ濃度が前記１層の内部電極層の平均Ｓｎ濃度よりも高いＳｎ高濃度部が形成されていることを特徴とする。【選択図】図５
