PROBLEM TO BE SOLVED : To provide a method of producing a rare-earth magnet capable of producing a rare-earth magnet having a sufficiently excellent magnetic characteristic. SOLUTION : This method of producing a rare-earth magnet containing a rare-earth compound containing a first rare-earth element and a second rare-earth element includes : a mixing step of mixing rare-earth compound powder including the first rare-earth element and subjected to a process based on a hydrogenation-dehydrogenation recombination method with a diffusion material containing the second rare-earth element different from the first rare-earth element; a molding step of molding the mixed powder in a magnetic field to manufacture a compact; and a heating step of heating the compact to diffuse the second rare-earth element into the rare-earth compound powder.
