PROBLEM TO BE SOLVED : To provide a production method of rare-earth magnet in which higher magnetization is achieved by hot plastic processing while ensuring a high coercive-force simultaneously. SOLUTION : In the method of producing an R-T-B-based rare-earth magnet by performing hot plastic processing after molding the powder of an R-T-B-based rare-earth alloy (R : rare-earth element, T : Fe or a part of Fe is replaced by Co), the hot plastic processing is performed in a processing direction different from the molding.
