PROBLEM TO BE SOLVED : To provide a method for manufacturing a rare-earth magnet capable of simply and easily obtaining a rare-earth magnet having a high residual magnetic flux density, and to provide a rare-earth magnet can be obtained by the manufacturing method.
SOLUTION : The method for manufacturing the rare-earth magnet comprises the steps of blending a magnetic powder, molding the magnetic powder, and sintering the molded magnetic powder. In the blending step of the magnetic powder, a first magnetic powder comprising a magnetic material including a rare-earth element, a transition element, and a boron (B), and having an average grain diameter of not more than 10 μm; and a second magnetic powder comprising a magnetic material including a rare-earth element, a transition element, and a boron (B), and having a second average grain diameter of not more than 10 μm and different from the first average grain diameter are mixed.
