简介 PROBLEM TO BE SOLVED : To provide a method for manufacturing a rare earth magnet by which a rare earth magnet superior in magnetic property can be manufacture with good productivity. SOLUTION : A method for manufacturing a rare earth magnet comprises the steps of : preparing hydrogenated powder 30 composed of a hydrogenated alloy including a rare earth element hydrogen compound and an iron group element, and anisotropic magnet powder 20 including a rare earth element and having crystal magnetic anisotropy; producing a powder compact 100 by press-compacting a powder mixture 110 including the hydrogenated powder and the anisotropic magnet powder while applying a magnetic field thereto; and performing a dehydrogenation treatment on the powder compact to cause the recombination in the hydrogenated alloy and thus, manufacturing a magnet material 10 in which particles of the anisotropic magnet powder are bonded to each other by the recombined alloy.
