PROBLEM TO BE SOLVED : To provide a rare earth permanent magnet improved in magnetic characteristics of a permanent magnet by being appropriately subjected to magnetic field orientation, and a method for producing a rare earth permanent magnet.
SOLUTION : A compound 12 is formed by : pulverizing a magnet raw material into magnet powder; and mixing the pulverized magnet powder and a binder. Then, a green sheet 14 is prepared by molding the formed compound 12 in a sheet form on a support substrate 13 by hot melt molding. The molded green sheet 14 is thereafter heated to be softened, and the heated green sheet 14 is subjected to magnetic field orientation by being applied with a magnetic field. The green sheet 14 after the magnetic field orientation is further sintered to produce a permanent magnet 1.
