A spindle motor is provided in which an end portion of a winding of a coil maintains insulation from a base and the end portion of the winding of the coil can be easily threaded through a hole of a printed circuit board when the end portion of the winding of the coil is drawn out. For this, the spindle motor includes a base fixed with a stator having a coil, an insulating sheet provided between the stator and the base, and a printed circuit board provided in the base on an outer side of the motor. Holes are formed in the base, insulating sheet and printed circuit board so as to communicate with each other, and an winding end portion of the coil is led out to the outside of the motor. The diameter C of the hole 19 in the printed circuit board and the diameter B of the hole 18 of the insulating sheet are smaller than the diameter A of the hole 17 of the base, and the diameter C of the hole 19 is larger than the diameter B of the hole 18.
