To use a thermosetting adhesive to bond a sleeve and a shaft of a rotor inserted with the rotor and a base, and to manufacture a motor at a low cost.

The rotor 11 and a stator 13 are held by a positioning jig 5. In this state, the sleeve 121 is inserted into a hole 1311 of a base bracket 131 with the thermosetting adhesive 3 applied thereto. The sleeve 121 is temporarily fixed to the base bracket 131 by high-frequency induction heating using an induction coil 42. Thereafter, a temporarily-fixed motor 1 is heated in an oven to properly cure the adhesive 3. The use of the thermosetting adhesive 3 makes it possible to reduce the occurrence of outgassing after assembling. Since the sleeve 121 is temporarily fixed by heating from the back side of the base bracket 131, a large scale jig is unnecessary for actual curing which requires a plenty of time. As a result, the motor can be manufactured at a low cost.
