PROBLEM TO BE SOLVED : To provide a method of manufacturing a rare earth sintered magnet, enhancing a residual magnetic flux density, and improving a removability of solvent in wet press forming, to improve productivity and economic efficiency.
SOLUTION : The method of manufacturing a rare earth sintered magnet includes steps of : feeding slurry which includes rare earth magnetic powder and solvent, into a cavity of a forming machine and applying a static magnetic field to the slurry in a cavity in a first direction (a first step of applying a static magnetic field S14a); and applying a static magnetic field in a second direction differing from the first direction (a second step of applying a static magnetic field S14b), and then pressure-forming the slurry under the state of applying a constant static magnetic field (a step of wet forming S14).
