A low-profile motor includes a rotor yoke having a rotor magnet on its inner or outer surface and being rotationally supported on a motor base via a shaft, and a stator core constituted of a plurality of T-shaped winding parts each having an end opposed to the rotor magnet. On the motor base formed with a hole for supporting the rotor yoke via the shaft, the plurality of T-shaped winding parts are cut like tongues along the radial direction of the hole, and the T-shaped winding parts are each bent such that their ends are opposed to the rotor magnet. Thus, it is possible to readily form the T-shaped winding parts, eliminate the need for mounting the T-shaped winding parts, and reduce the number of parts and steps. This technique enables it to efficiently form an inexpensive low-profile motor for a magnetic disk unit and the like.
