PROBLEM TO BE SOLVED : To provide a method of manufacturing a rare-earth magnet having superior magnetic properties which is carried out, in such a way that a rare-earth permanent magnet having a nanocomposite structure is produced by plating on raw material powder. SOLUTION : This method of producing a rare-earth magnet comprises steps of plating materials containing metal elements on magnetic powder, including rare-earth elements, by using a plating solution which contain at least one metal atom compound, selected from among a group consisting of Fe, Ni, Co, and Mn, and amine compounds to form the ions and complexes of the metal atom and the pH of which is 8-12, and forming the magnetic powder after the plating process.
