Claim:
1. A method of manufacturing a fluid bearing apparatus including a plated bearing member, the method comprising the steps of: a) plating a metallic base material including a cylindrical base material inner circumferential surface to define a plating layer on the base material inner circumferential surface; and b) bringing a contact portion of a pressing member into contact with the plating layer after step a); wherein at least a portion of the pressing member including the contact portion has a Young's modulus equal to or greater than a Young's modulus of the base material; in step b), by bringing the pressing member into contact with the plating layer, a surface of the plating layer is smoothened without causing plastic deformation of the base material; every point on the surface of the plating layer is equidistant or substantially equidistant from a central axis; the pressing member contact portion is a single contact portion, the single contact portion being annular and every point on the contact portion being equidistant or substantially equidistant from the central axis, or the pressing member includes a plurality of contact portions, every point on each contact portion being equidistant or substantially equidistant from the central axis; and in step b), a difference between a distance from the central axis to the contact portion and a distance from the central axis to the surface of the plating layer is equal or substantially equal to an average layer thickness of the plating layer or smaller than the average layer thickness of the plating layer.
