PURPOSE: To increase the difference in magnetic characteristics between both flat surfaces of a flat magnet and to improve the magnetic characteristic on the flat surface side by interposing a nonmagnetic body between the upper punch consisting of a magnetic material and the upper end part of a die having a molding space, and compression-molding the magnet.

CONSTITUTION: A slurry powdered material is filled into the molding space of a die 1 in the molding apparatus of an anisotropic ferrite magnet, and then a coil 6 is excited to form a magnetic field. The die 1, an upper punch 5, and a core 3 are moved down to compression-mold an anisotropic ferrite magnet. A nonmagnetic plate 4 is provided between the powdered material and the surface of the upper punch 5 on the molding space side which is in contact with the powdered material. Besides, the thickness T of the nonmagnetic plate 4 is increased continuously or stepwise from the periphery of the upper punch 5 toward the central perpendicular of the molding space while keeping the contact surface of the plate with the powdered material flat.
