description	A method comprises: charging a rare-earth magnet-forming material comprising magnet material particles into a mold, in a state in which an easy magnetization axis of each of the magnet material particles is oriented in one plane; sintering the rare-earth magnet-forming material charged in the mold by heating the rare-earth magnet-forming material to a sintering temperature while applying a given magnitude of pressing force to the rare-earth magnet-forming material, to thereby form a sintered body in which the magnet material particles are integrally sintered; and then subjecting the sintered body to high-temperature heat treatment, under a pressure lower than the pressing force during the sintering and under a maximum achieving temperature which ranges from greater than 900° C. to 1100° C., and whose difference from a maximum achieving temperature during the pressure sintering is within 250° C.
