Abstract: A lead wire guide member is made of an electrically insulating material, and arranged to extend along a lower surface of a base portion. A movement restricting portion is arranged in the lower surface of the base portion. Lead wires are arranged to pass through base through holes to reach the lower surface, and extend along the lower surface to be connected to the circuit board. A spindle motor further includes a sealant arranged between an entire circumferential extent of each base through hole and an entire circumferential extent of the corresponding lead wire. The lead wire guide member includes an inner edge and an outer edge. The inner edge is arranged opposite to the lead wires. The outer edge is arranged to at least face radially outward. The movement restricting portion is in contact with the outer edge of the lead wire guide member.
