It provides a method of producing a barrel-shaped bonded magnet and the tubular casing is tightly squeezed case integrated bonded magnet efficiently. Method for producing a case-integrated bonded magnet of the present invention, the filling step of filling the magnet raw material including at least one rare-earth magnet powder and a thermosetting resin which is a binder in the cylindrical cavity and soften the thermosetting resin by heating the magnet raw material state or while in a molten state, and the heated molding process by compression molding a magnetic material to obtain a tubular shaped body, in the cylindrical cavity and a metallic cylindrical case having an inner circumferential surface of the shaft, press-fitting, while discharging the tubular molded article from the tubular cavity discharged to the press-in process and, by heating the tubular shaped body with a tubular casing and a thermal curing process for curing the thermosetting resin. By heat curing the tubular press-formed article in the cylindrical case, the tubular molded article is changed cylindrical bonded magnet, the thermal expansion by more than assumed. As a result, the tubular casing and barrel-shaped bonded magnet is rigidly pressed casing integrated bonded magnet obtained.
