LAMINATE TYPE ELECTRONIC COMPONENT
To provide a laminate type electronic component by which high reliability can be ensured.SOLUTION: A dielectric layer 11 contains, as elements, Ba, Ti, Si, Re which is a rare earth element, and M (M is at least one element selected from among Mn, Ni, Co, Fe, Cr, Cu, Mg, Li, Al, Mo, W and V). The laminate 10 has: an electrode mutually-opposed part 13a where internal electrode layers 12 are opposed to each other through the respective dielectric layers 11; and an outer peripheral portion 13b surrounding the electrode mutually-opposed part 13a. When amounts of the elements included in the dielectric layer 11 in the electrode mutually-opposed part 13a are represented by pts.mol, a Si amount a satisfies 0.01≤a≤0.1, a Re amount b satisfies 0.1≤b≤3.0, an M amount c satisfies 0.2≤c≤5.0, assuming that a Ti amount is 100. A ratio m of a Ba amount to a Ti amount satisfies 0.965≤m≤0.990.SELECTED DRAWING: Figure 1
【課題】高い信頼性が確保できる積層型電子部品を提供する。【解決手段】誘電体層１１は、元素としてＢａと、Ｔｉと、Ｓｉと、希土類元素であるＲｅと、Ｍ（Ｍは、Ｍｎ、Ｎｉ、Ｃｏ、Ｆｅ、Ｃｒ、Ｃｕ、Ｍｇ、Ｌｉ、Ａｌ、Ｍｏ、ＷおよびＶの中から選ばれる少なくとも１種類の元素）とを含む。積層体１０は、複数の内部電極層１２がそれぞれ誘電体層１１を介して相対している電極相対部１３ａと、電極相対部１３ａを囲む外周部１３ｂとを有する。電極相対部１３ａにおける誘電体層１１に含まれる元素の量をモル部で表した場合、Ｔｉの量を１００としたときに、Ｓｉの量ａが、０．０１≦ａ≦０．１、Ｒｅの量ｂが、０．１≦ｂ≦３．０、Ｍの量ｃが、０．２≦ｃ≦５．０である。Ｂａの量のＴｉの量に対する比ｍは、０．９６５≦ｍ≦０．９９０である。【選択図】図１
