A method for producing a soft magnetic material comprises a step wherein a plurality of composite magnetic particles, each of which is composed of a metal magnetic particle and an insulating coating film covering the surface of the metal magnetic particle, are formed into a compaction, and another step wherein the compaction is subjected to a heat treatment at not less than 400° C. and not more than 900° C. The insulating coating film contains at least one element selected from the group consisting of sulfur, selenium, titanium and aluminum. By having such a constitution, the resulting soft magnetic material can have desired magnetic characteristics.
