PROBLEM TO BE SOLVED : To provide a manufacturing method which enables the user to simply manufacture a rare earth permanent magnet, where a plurality of plate-shaped permanent magnets are stacked via nonconductive resin, out of one block-shaped permanent magnet. SOLUTION : A rare earth permanent magnet for a motor consisting of such constitution that a plurality of plate-shaped permanent magnets are stacked through nonconductive resin can be obtained, by forming a plurality of slits of fixed length, from its one side to its opposite side, in a rectangular rare earth permanent magnet, thereby forming a divided part and a yoke part which retains magnets divided at the above slit ends, and then, charging the slit with nonconductive resin, and further, separating the divided part and the yoke part.
