PROBLEM TO BE SOLVED : To provide a method of manufacturing a rare earth bond magnet capable of obtaining an injection molding rare earth bond magnet having excellent rust-prevention by forming a satisfactory metal-plated layer on the surface of an injection-molded rare earth bond magnet. SOLUTION : The method includes : a process for injecting a mixture of rare earth magnetic powder and a thermoplastic resin binder to obtain a magnet forming body; a process for polishing the surface of the magnet forming body to expose the rare earth magnetic powder; and a process for forming the metal-plated layer on the surface of the polished magnet forming body. As polishing media, vegetable polishing media are used. COPYRIGHT : (C)2009, JPO&INPIT
