Abstract
A base member of a spindle motor includes a base through-hole and a base groove portion. The base through-hole extends through a bottom portion of the base member. The base groove portion is arranged on a lower surface of the base member to extend radially outward from the lower end portion of the base through-hole. A first insulating sheet portion is fixed to a bottom surface of the base groove portion by an adhesive agent or sticky material. Lead wires extending from coils are led out into the base groove portion through the base through-hole. The lead wires extend outward along a lower surface of the first insulating sheet portion. The lead wires are soldered to land portions of a circuit substrate at an outer side of the bottom portion. A portion of the first insulating sheet portion overlaps with a lower opening of the base through-hole in plan view.
