PROBLEM TO BE SOLVED: To prevent drop out of a bearing sleeve caused by difference of linear expansion coefficients between the bearing sleeve and a housing adhered and fixed to each other in a fluid bearing device and to provide high fixing strength between the same. SOLUTION: A large diameter part 15 is provided at an upper end in an axial direction of a first sleeve part 11, and a lower end surface 15a of the large diameter part 15 and an upper end part 10d of the housing part 10 butting on the lower end surface 15a in an axial direction under a condition that the first sleeve part 11 is inserted in an inner circumference of the housing part 10 are adhered and fixed. A large diameter part 16 is provided at a lower end in an axial direction of a second sleeve part 12, and a lower end surface 16a of the large diameter part 16 and a lower end part 10e of the housing part 10 abutting on the upper end surface 16a in an axial direction under a condition that the second sleeve part 12 is inserted in the inner circumference of the housing part 10 are adhered and fixed together.
