PROBLEM TO BE SOLVED: To provide a fluid bearing device that can maintain desired bearing performance stably at low cost. SOLUTION: The fluid bearing device 1 includes a bearing member 6, which includes a sleeve part 8 that forms a radial bearing space between the bearing member and a shaft member 2 accommodated on the inside circumference, and a housing part 7, on the inside circumference of which the sleeve part 8 is arranged; lubricating oil, which fills the inside space of the bearing member; and a circulation hole 11 in the axial direction, which opens on both end surfaces of the bearing member 6. The lubricating oil is enabled to flow and circulate via the circulation hole 11 in the axial direction. After the circulation hole 11 is opened in the sleeve part 8 by laser processing, the sleeve part 8 is inserted into the housing part 7, which is formed by injection molding with a molten resin.
