To provide a fluid bearing device at a low cost which can stably keep a required bearing performance.
The fluid bearing device 1 comprises a bearing member 6 having a sleeve portion 8 forming a radial bearing clearance between the sleeve portion 8 and a shaft member 2 retained in the inner circumference of the sleeve portion 8 and having a housing portion 7 retaining the sleeve portion 8 in the inner circumference of the housing portion 7, and lubricating oil for filling the radial bearing clearance. The lubricating oil can circularly flow through an axial circulation passage 11 formed in the bearing member 6. The circulation passage 11 is formed by being irradiated with a laser beam after the sleeve portion 8 has been inserted and the housing portion 7 has been formed by the injection molding.
