ABSTRACT:
This invention provides a soft magnetic yoke-integrated bonded magnet in which a soft magnetic yoke has been integrally compression molded in such a state that the soft magnetic yoke is engaged in a joined face formed by bringing a binding material-containing magnetic powder into contact with a binding material-containing soft magnetic powder. The soft magnetic yoke part and the bonded magnetic part are constructed so that, when the soft magnetic yoke part and the bonded magnet part are compression molded separately from each other, the spring back level is identical upon the release of the compression force.
