LAMINATED COIL COMPONENT
To provide a laminated coil component having excellent magnetic characteristics such as magnetic permeability, insulation resistance and dielectric constant, and frequency characteristics in addition to sinterability.SOLUTION: In a laminated coil component 1 according to the present invention, a sintered material that constitutes an insulating layer 31 between coil conductors 32 includes 8 mol% or more and 37 mol% or less of Fe2O3 converted from Fe, 30 mol% or more and 60 mol% or less of ZnO converted from Zn, 1 mol% or more and 7 mol% or less of CuO converted from Cu, 3 mol% or more and 17 mol% or less of NiO converted from Ni, and 7 mol% or more and 28 mol% or less of SiO2 converted from Si. The molar ratio between SiO2 converted from Si and Fe2O3 converted from Fe in the sintered material (SiO2/Fe2O3) is 0.2 or more and 3.5 or less.SELECTED DRAWING: Figure 3
【課題】焼結性に加え、透磁率、絶縁抵抗及び誘電率等の磁気特性並びに周波数特性に優れる積層型コイル部品を提供する。【解決手段】本発明の積層型コイル部品１は、コイル導体間３２の絶縁層３１を構成する焼結材料が、ＦｅをＦｅ２Ｏ３に換算して８ｍｏｌ％以上、３７ｍｏｌ％以下、ＺｎをＺｎＯに換算して３０ｍｏｌ％以上、６０ｍｏｌ％以下、ＣｕをＣｕＯに換算して１ｍｏｌ％以上、７ｍｏｌ％以下、ＮｉをＮｉＯに換算して３ｍｏｌ％以上、１７ｍｏｌ％以下、ＳｉをＳｉＯ２に換算して７ｍｏｌ％以上、２８ｍｏｌ％以下含む。焼結材料中のＳｉ及びＦｅをそれぞれ、ＳｉＯ２及びＦｅ２Ｏ３に換算したときのＳｉＯ２と、上記Ｆｅ２Ｏ３のモル比（ＳｉＯ２／Ｆｅ２Ｏ３）が０．２以上、３．５以下である。【選択図】図３
