A base plate includes a base body including a bottom plate and a pivot post, and an electrodeposition coating film. The bottom plate extends perpendicular to a first axis, a rotation axis of the disk, and a second axis, a swing axis of a head; and, when viewed from an axial direction, has a rectangular shape with a first direction as a short side direction and a second direction as a long side direction. The pivot post protrudes upward from an upper surface of the bottom plate at a position overlapping the second axis. The bottom plate has a thin bottom arranged in a radially outward direction orthogonal to the second axis of the pivot post and including at least one of a lower recess recessed upward from a lower surface of the bottom plate and an upper recess recessed downward from the upper surface of the bottom plate.
