Abstract
A spindle motor includes a rotating part, a base member, a connector, and a connector accommodating recess in the base member. The connector accommodating recess includes a bottom surface and an annular wall surface extending from the bottom surface to the outer surface. A through-hole is formed in the bottom surface. The bottom surface includes a first annular surface extending toward the annular wall surface from a peripheral edge of the through-hole, and a second annular surface extending around the first annular surface on an axial outer surface side of the base member relatively to the first annular surface. The connector contacts the second annular surface. A first gap between the connector and the first annular surface is filled with an adhesive. An interface of the adhesive extends i to protrude from an inner peripheral surface of the through-hole over an entire circumference of the through-hole.
