Abstract: A material containing a soft magnetic substance is subjected to a plastic deformation such as a roll processing to obtain a rod-shaped body. Then, the rod-shaped body or a shaped body obtained by processing the rod-shaped body into a shape other than a flat plate shape is subjected to a heat treatment in the presence of a magnetic field. The rod-shaped body or the shaped body is made magnetic-anisotropic by the heat treatment thereby to obtain a magnetic-anisotropic plastically deformed body.
