PROBLEM TO BE SOLVED: To provide a multilayer ceramic electronic component increased in capacitance and also high in dielectric breakdown voltage and insulation resistance.SOLUTION: A multilayer ceramic electronic component includes a ceramic body which has a dielectric layer 111 and in which internal electrodes 121, 122 are alternately stacked. The dielectric layer includes at least one dielectric grain 11 which has a ratio of a major axis to a minor axis of 3.5 or more. The internal electrodes include a ceramic common material containing a grain growth adjusting ingredient for dielectric grains. The dielectric layer includes interfacial portions adjacent to the internal electrodes and a central portion disposed between the interfacial portions, and concentrations of the grain growth adjusting ingredient in the interfacial portions and the central portion are different from each other.SELECTED DRAWING: Figure 3 【課題】本発明は、容量が増加すると共に、絶縁破壊電圧が高く、絶縁抵抗の高い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、誘電体層１１１を有し、内部電極１２１，１２２が交互に積層されたセラミック本体を含み、誘電体層は短軸に対する長軸の比が３．５以上である誘電体グレイン１１を少なくとも一つ以上含み、上記内部電極は誘電体グレインの粒成長調節成分を含むセラミック共材を含んでいる。上記誘電体層は、上記内部電極と隣接した界面部、及び上記界面部の間に配置される中央部で構成され、上記界面部と中央部の粒成長調節成分の濃度が異なっている。【選択図】図３
