PROBLEM TO BE SOLVED : To provide a method of manufacturing a rare-earth sintered magnet by obtaining a mold by isostatic pressing after orientation in a pulse magnetic field, wherein a high-performance magnet is obtained by improving the orientation rate even when a rare-earth magnet alloy having a high coercive force is used. SOLUTION : A rare-earth magnet alloy whose coercive force is made low by occluding hydrogen is pulverized, and the powder is oriented by a pulse magnetic field. Then, a mold is obtained by isostatic pressing. This mold is dehydrogenated, sintered, and subjected to aging to manufacture a rear-earth sintered magnet.
