PURPOSE: To acquire a resin bond type magnet of high strength whose dimensional accuracy is high and resistance to raising of dusts and corrosion is high by impregnating anaerobic resin.

CONSTITUTION: Anaerobic resin is impregnated into a resin bond-type magnet to fill up vacancy. Since the anaerobic resin is cut off from air, a resin bond type magnet of high strength whose dimensional accuracy is high and resistance to raising of dusts and corrosion is high can be acquired due to its characteristic of setting at a room temperature or 80°C or lower.
