Abstract

　磁性層と非磁性層の界面における割れ、欠け、剥離の発生や、積層体の反りなどの発生を抑制、防止することが可能で、磁気飽和しにくく、直流重畳特性に優れた、開磁路型の積層コイル部品を提供する。 　磁性層と、非磁性層または低透磁率層とを積層してなる積層体１１と、その内部に配設されたコイル導体５とを備えた、開磁路型の積層コイル部品１において、積層体１１を構成する非磁性層または低透磁率層に、酸化ジルコニウムを含有させる。 　低透磁率層の酸化ジルコニウムの含有量を、０．０２重量％以上、１．０重量％未満とする。 　また、磁性層にも１．０重量％未満の割合で酸化ジルコニウムを含有させる。 　磁性層としてＮｉ－Ｃｕ－Ｚｎ系フェライト、非磁性層または低透磁率層としてＣｕ－Ｚｎ系フェライトをそれぞれ主成分とする材料からなるものを用いる。
