    摘要: A soft magnetic material is a soft magnetic material including a composite magnetic particle (30) having a metal magnetic particle (10) mainly composed of Fe and an insulating coating (20) covering metal magnetic particle (10), and insulating coating (20) contains an iron phosphate compound and an aluminum phosphate compound. The atomic ratio of Fe contained in a contact surface of insulating coating (20) in contact with metal magnetic particle (10) is larger than the atomic ratio of Fe contained in the surface of insulating coating (20). The atomic ratio of Al contained in the contact surface of insulating coating (20) in contact with metal magnetic particle (10) is smaller than the atomic ratio of Al contained in the surface of insulating coating (20). Thus, iron loss can be reduced.
