A soft magnetic powder material includes an iron powder, and a plated layer formed on a surface of the iron powder and possessing a lubricating property. The plated layer includes a lubricant material and a matrix in which the lubricant material disperses. The soft magnetic powder material is manufactured by an electroless deposition process, by which a plated layer is formed by depositing, on a surface of an iron powder, at least one element building a matrix, along with a micro-powdered lubricant material.

A soft magnetism metal powder having a majority of particles, each of which, when cross-sectioned, has no greater than ten crystal particles on average, may be coated on an outer surface of each of the particles with a resistive material having a higher resistivity than the underlying parent phase. The soft magnetism metal powder may be prepared by heating a soft magnetism metal powder to a high temperature in a high temperature atmosphere, thereby reducing the number of crystal particles in each of the soft magnetism metal powder particles. A soft magnetism metal formed body may be prepared by pressing the soft magnetism metal particles at a sufficient temperature and pressure.
