The present invention makes it possible to increase the residual magnetic flux density and the coercive force of a rare earth magnet; and raise the Curie temperature. In a magnet formed by compressing magnetic particles, the surface of a magnetic particle is covered with a metal fluoride film, the magnetic particle has a crystal structure containing a homo portion formed by bonding adjacent iron atoms and a hetero portion formed by bonding two iron atoms via an atom other than iron, and the distance between the two iron atoms in the hetero portion is different from the distance between the adjacent iron atoms in the homo portion.
