Beschreibung
Zusammenfassung:	A method for producing a rare-earth alloy based binderless magnet according to the present invention includes the steps of: (A) providing a rapidly solidified rare-earth alloy magnetic powder 2; and (B) compressing and compacting the rapidly solidified rare-earth alloy magnetic powder 2 by a cold process without using a resin binder, thereby obtaining a compressed compact 10, 70 vol% to 95 vol% of which is the rapidly solidified rare-earth alloy magnetic powder 2.
