Abstract:
A spindle motor includes a stationary unit, a rotary unit and a bearing mechanism. The stationary unit includes a base member, a stator including a plurality of coils and a wiring substrate electrically connected to the stator. The base member includes a tubular portion, a first accommodation portion, an opening portion, a plurality of coil accommodation portions, a second accommodation portion, and at least one through-hole. The wiring substrate includes an arc portion and an extension portion. A lead wire is led out from at least one of the coils and is connected to the arc portion by soldering within the through-hole.
