To provide a laminate electronic component.SOLUTION: A laminate electronic component includes a dielectric layer having a plurality of dielectric crystal grains. At least one of the dielectric crystal grains has a core-interface shell-shell structure. The dielectric crystal grain having a core-interface shell-shell structure includes a perovskite (ABO3)-based base material main component; a first sub-component containing Si; and a second sub-component including at least one selected from the group of Mn, V, Cr, Fe, Ni, Co, Cu, Zn, and Sn. The average content of the first sub-component is largest in a first interface shell region and the average content of the second sub-component is largest in a second interface shell region.SELECTED DRAWING: Figure 4 【課題】積層型電子部品に関する。【解決手段】誘電体層を含む積層型電子部品において、上記誘電体層は複数の誘電体結晶粒を含み、上記複数の誘電体結晶粒のうち少なくとも１つ以上は、コア－インターフェースシェル－シェル構造を有し、上記コア－インターフェースシェル－シェル構造を有する誘電体結晶粒は、ペロブスカイト（ＡＢＯ３）系母材主成分、Ｓｉを含む第１副成分、並びにＭｎ、Ｖ、Ｃｒ、Ｆｅ、Ｎｉ、Ｃｏ、Ｃｕ、Ｚｎ及びＳｎからなる群から選択された１つ以上を含む第２副成分を含み、上記第１副成分の平均含有量は第１インターフェースシェル領域で最も高く、上記第２副成分の平均含有量は上記第２インターフェースシェル領域で最も高いことができる。【選択図】図４
