Abstract
A spindle motor includes a shaft arranged in an upward/downward direction along a central axis; a base member including a substantially cylindrical holder portion arranged around the central axis; a bearing unit arranged radially inward of the holder portion; and a rotating portion arranged above the base member to rotate about the central axis. The rotating portion preferably includes a mounting surface on which a disk is to be mounted. An adhesive containing an electrically conductive material and an adhesive containing an externally stimulated curing material and/or an anaerobic curing material are arranged in a clearance space defined between an inner circumferential surface of the holder portion and an outer circumferential surface of the bearing unit. The adhesive containing the electrically conductive material is arranged above the adhesive containing the externally stimulated curing material and/or the anaerobic curing material.
