Composite magnetic body composition, magnetic member, and electronic component

[Problem] To provide: a highly reliable magnetic member which has good heat resistance and is capable of suppressing deterioration in characteristics over a long period of time; a composite magnetic body composition which constitutes the magnetic member; and an electronic component which has the magnetic member. [Solution] A composite magnetic material composition (10) has: a binder (14) containing a bisphenol-type epoxy resin in which molecular rotation is suppressed; and a plurality of magnetic particles (12) bonded by a binder (14). [技术问题]本发明提供一种耐热性良好且能够长期地抑制特性劣化的高可靠性的磁性构件、构成该磁性构件的复合磁性体组合物、以及具有该磁性构件的电子部件。[解决方案]复合磁性体组合物(10)具有：粘合剂(14)，其包含分子旋转被抑制的双酚型环氧树脂；以及多个磁性颗粒(12)，其被粘合剂(14)粘结。
