A method for producing a rare-earth magnet, in a process of applying a slurry obtained by dispersing a powder containing at least one selected from an oxide, a fluoride, an oxyfluoride, a hydroxide or a hydride of R 2, R 2 is at least one selected from rare-earth elements including Y and Sc, in a solvent to a sintered magnet body composed of a R 1 -Fe-B composition, R 1 is at least one selected from rare-earth elements including Y and Sc, drying the slurry to cause a surface of the sintered magnet body to be coated with the powder, and heat treating the powder-coated sintered magnet body to cause the R 2 to be absorbed into the sintered magnet body and thereby to produce a rare-earth permanent magnet, the method comprising: holding a plurality of the sintered magnet bodies by a rotatable jig; immersing the sintered magnet bodies in the slurry obtained by dispersing the powder to coat each of the sintered magnet bodies with the slurry; drawing the slurry-coated sintered magnet bodies up from the slurry and rotating the sintered magnet bodies together with the jig to remove surplus slurry on the surface of each of the sintered magnet bodies by a centrifugal force; and drying the slurry-coated sintered magnet bodies to coat the surfaces of the sintered magnet bodies with the powder, wherein the sintered magnet bodies are in a shape of a tetragonal plate or a tetragonal block, the slurry is applied while the sintered magnet bodies are disposed around a rotational axis of the jig, characterized in that each of the sintered magnet bodies is held by the jig in a state in which the sintered magnet body is erect with its thickness direction set horizontal and with its length direction or width direction inclined at an angle (r) of more than 0° and less than 45° from the direction of the centrifugal force so that the sintered magnet bodies are inclined such that no part of any of outer surfaces constituting shapes of the sintered magnet bodies is orthogonal to the direction of the centrifugal force. holding a plurality of the sintered magnet bodies by a rotatable jig; immersing the sintered magnet bodies in the slurry obtained by dispersing the powder to coat each of the sintered magnet bodies with the slurry; drawing the slurry-coated sintered magnet bodies up from the slurry and rotating the sintered magnet bodies together with the jig to remove surplus slurry on the surface of each of the sintered magnet bodies by a centrifugal force; and drying the slurry-coated sintered magnet bodies to coat the surfaces of the sintered magnet bodies with the powder, wherein the sintered magnet bodies are in a shape of a tetragonal plate or a tetragonal block, the slurry is applied while the sintered magnet bodies are disposed around a rotational axis of the jig, characterized in that each of the sintered magnet bodies is held by the jig in a state in which the sintered magnet body is erect with its thickness direction set horizontal and with its length direction or width direction inclined at an angle (r) of more than 0° and less than 45° from the direction of the centrifugal force so that the sintered magnet bodies are inclined such that no part of any of outer surfaces constituting shapes of the sintered magnet bodies is orthogonal to the direction of the centrifugal force.
