    摘要: A soft magnetic material includes a plurality of composite magnetic particles (30), wherein each of the plurality of composite magnetic particles (30) includes a metal magnetic particle (10), an insulating coating (20) covering the surface of the metal magnetic particle (10), and a composite coating (22) covering the outside of the insulating coating (20). The composite coating (22) includes a heat-resistance-imparting protective coating (24) covering the surface of the insulating coating (20), and a flexible protective coating (26) covering the surface of the heat-resistance-imparting protective coating (24). Accordingly, a soft magnetic material and a dust core which have a satisfactory compactibility and in which the insulating coating satisfactorily functions, thereby sufficiently reducing core loss, can be obtained.

    摘要: A soft magnetic material includes a plurality of composite magnetic particles each including a metal magnetic particle and an insulating coating film covering the metal magnetic particle. Each of the plurality of composite magnetic particles has a ratio Rm/c of a maximum diameter to a circle-equivalent diameter of more than 1.15 and not more than 1.35. The insulating coating film is composed of a thermosetting organic material and has a pencil hardness of 5H or higher after thermosetting. With this material, an eddy current loss can be reduced, and a compact with a high strength can be formed.
