A head actuator of a disk device has a support frame formed of metal. A voice coil of a voice coil motor has a winding central axis that extends substantially parallel to a rotation axis of the head actuator. An outer peripheral portion of the voice coil has opposite outer peripheral portions opposed to the support frame and an exposed outer peripheral portion situated on the outermost periphery with respect to the bearing portion. The voice coil is fixed to the support frame with a resin molded between the support frame and the opposite outer peripheral portions. A lead wire of the voice coil is covered by a molded resin and fixed in a predetermined position on the head actuator. Annular upper and lower surfaces and the exposed outer peripheral portion of the voice coil are exposed to the outside without being covered with the resin.
