Abstract: A rotating device includes: a hub mounting a recording disk; a base rotatably supporting the hub via a bearing, a core fixedly mounted on the base, and having a circular portion and salient poles protruding radially outward; a coil wound around the salient poles; and an FPC including driving lines. The base has a wire hole that communicates between an upper face that faces the coil in the axial direction and an opposite lower face. The lower face has a bottom recess portion surrounding a hub rotational axis, and regions facing each other across the rotational axis. The FPC includes an arc section housed in the bottom recess portion. Each lead wire is drawn out from the coil to the lower-face side via the wire hole, and is connected to the driving line on a connection land formed at an interval from the wire hole in the circumferential direction.
