Abstract: Disclosed are a method of manufacturing a rare-earth permanent magnet capable of offsetting a partially uneven demagnetization by varying the amount of heavy rare-earth element diffused to a grain boundary for each region and a Nd—Fe—B-based permanent magnet manufactured by the same. The method includes: preparing a base material including a plurality of regions by using a sintered magnet including an Nd—Fe—B-based alloy; preparing a coating material including a heavy rare-earth element; applying the coating material to a surface of the base material; and diffusing the heavy rare-earth element to a grain boundary of the base material by heat-treating the base material to which the coating material is applied. In the applying the coating material, an amount of the coating material applied to each region of the base material may vary.
