PROBLEM TO BE SOLVED : To provide an improved Nd-Fe-B based magnet manufacturing method. SOLUTION : A manufacturing method of a permanent magnet includes a step for supplying an alloy powder 10 containing at least one rare earth element. The alloy powder 10 is formed within a metal die 12 and then exposed under microwave radiation 14 or a pulse-like current, thereby forming a sintered magnet 16. COPYRIGHT : (C)2014, JPO&INPIT
