Summary:PURPOSE:To obtain the method for manufacture of a rare earth-iron-nitrogen bonded magnet of rubberlike elasticity at room temperature by rolling. CONSTITUTION:In the bonded magnet manufacturing method in which a bonded magnet is molded using rare earth-iron-nitrogen magnet powder and resin, a bonded magnet, having rubber-like elasticity at room temperature and containing 70% of magnetic powder in volumetric percentage, is formed. In this bonded magnet manufacturing method, a method for formation of the mixture of magnet powder and resin by rolling is considered effective. Especially, when thermoplastic elastomer is used as resin, process can be simplified, and a high productivity can be obtained.
