Zusammenfassung:	Provided is a powder (1) for a magnetic core, including: a soft magnetic metal powder (2); an insulating coating (3) for covering a surface of the soft magnetic metal powder (2); and a lubricating coating (4) for covering a surface of the insulating coating (3). The lubricating coating (4) is formed by eliminating a solvent component and causing a lubricating component to adhere to a coated powder (1′) in a lubricant solution (26) supplied into a container (21) in which the coated powder (1′) is being stirred in a floating state, the coated powder being formed by covering the surface of the soft magnetic metal powder (2) with the insulating coating (3).
