摘要
A process for making soft magnetic material comprising: (i) a first heat treatment step of heating iron particles (10) having an average particle diameter of 5 to 300 microns at a temperature of 400 ° C to less than 900 ° C in hydrogen or an inert gas; (Ii) a step of forming a plurality of composite magnetic particles (30) in which the magnetic iron particles (10) are surrounded by an insulating film (20); and (iii) a step of forming a molded body by compacting the composite magnetic particles (30) at a pressure of 700-1500 MPa.
