PROBLEM TO BE SOLVED: To provide a method of producing soft magnetic iron-based powder for dust core, from which a dust core having a high maximum relative permeability can be obtained, while utilizing a prepared iron-based powder material effectively.SOLUTION: The method of producing soft magnetic iron-based powder for dust core includes a sintering step for sintering an iron-based powder material by heating in a reductive atmosphere, and a pulverization step for pulverizing the iron-based powder material thus sintered. The sintered iron-based powder material thus pulverized is made coarse for the iron-based powder material. |
