A composite magnetic material (1) comprising a plurality of composite magnetic particles (30) bonded to each other with an organic substance (40). The composite magnetic particle (30) includes a metallic magnetic particle (10) and a coating layer (20) bonded to the surface of the metallic magnetic particle (10) and containing a metal oxide or a metallic oxide magnetic substance. The organic substance (40) has a long-term heat-resisting temperature of 200 ° or higher. The organic substance (40) contains at least one kind selected from the group consisting of a thermoplastic resin having a ketone group, a thermoplastic polyether nitrile resin, a thermoplastic polyamide-imide resin, a thermosetting polyamide-imide resin, a thermoplastic polyimide resin, a thermosetting polyimide resin, a polyarylate resin, and a resin having fluoride.
