PURPOSE:To provide a method of manufacturing a bond magnet having high magnetic characteristics by uniformly and stably filling magnetic powder into a ring-shaped metal mold or the like containing radial orientation. CONSTITUTION:When a metal mold constituted of upper punches 1a, 1b, nonmagnetic members 2a, 2b, coils 3a, 3b, a yoke 4, magnetic powder 5a, 5b and a core pin 6 is filled with the magnetic powder to which magnetic field is previously applied, a filling part is filled with the powder in the state that magnetic field is applied by the coils 3a, 3b. Thereby an anisotropic bond magnet is manufactured. |
