The disk drive device includes a base member with a first upper surface and a second lower surface, a hub, a bearing unit arranged on the base member that rotatably supports the hub, a spindle drive unit that drives the hub to rotate, and a wiring member arranged on the second surface of the base member. The spindle drive unit includes a stator core having a salient pole with coil wound around, and a magnet opposed thereto. The base member includes a wire hole through which a wire is placed, with a first opening on the first surface and a second opening on the second surface. A concaved area on the second surface includes a lower slope, axially between the concaved area and the second opening on which a wiring member is arranged. The wire is connected to the wiring member, radially outside of an outer diameter of the magnet.
