Abstract (en)
A method for producing an anisotropic rare earth magnet is provided by extruding using a compacted material (20) formed in a shape having difference in level between the center part to be in contact with the end face of a punch (14) and the outer peripheral part to be faced with a molding cavity (18) formed between the punch (14) and a cylindrical die (10) of a mold (13). <IMAGE>
