Disclosed is a method for producing powder for a dust core capable of improving the quality and productivity of powder for a dust core, and which prevents formation of secondary particles when siliconizing. Also disclosed is a dust core that uses powder for a dust core produced using said method for producing powder for a dust core, and a device for producing powder for a dust core. In order to achieve same, only the soft magnetic metal powder (21) of a mixed powder (23) comprising soft magnetic metal powder (21) and powder for siliconizing containing silicon dioxide (22) is induction heated, which causes a heat transfer from the surface of the soft magnetic metal powder (21) to the powder for siliconizing (22), elemental silicon to detach from the powder for siliconizing (22), and the elemental silicon to be diffusion coated onto the surface of the soft magnetic metal powder (21), thereby forming a siliconized layer. |
