[Problem]Provide a method for producing thick-film rare earth magnets that have high magnetic properties and do not change the shape of magnets even when used in high temperature environments. [Solution means] The method for producing rare earth magnets is a magnet powder production step for obtaining rare earth-based magnet powder, a printing paste production step in which the rare earth-based magnet powder, a base resin, and an organic solvent are mixed to obtain a printing paste, and on a substrate, the printing paste is printed by screen printing, and at a temperature less than the boiling point of the organic solvent, A pre-drying step for drying the molded body, this drying and degreasing step for drying and degreasing the molded body at a temperature above the boiling point of the organic solvent, and the discharge plasma sintering (SPS) apparatus, under reduced pressure, the molded body is heated under pressure, and sintered to obtain a rare earth magnet.
