To increase the load capacity of a fluid bearing, and to reduce a flow rate of fluid required to operate the bearing.

This fluid bearing device includes: a bearing hole 7, into which a shaft 50 is to be inserted; fluid flow-in holes 9 and 10 opened in the peripheral surface of the fluid bearing 2 so that a fluid flows into them from outside; a fluid flow passage 11 surrounding the bearing hole 7 inside of the fluid bearing 2 and communicated with the fluid flow-in holes 9 and 10; and fluid throttles 14 and 15 communicating the fluid flow passage 11 with the bearing hole 7. A plurality of fluid flow-in holes 9 and 10 are provided, and the fluid flow passage 11 is partitioned by a plurality of divided fluid flow passages 12 and 13 corresponding to the fluid flow-in holes 9 and 10, and the divided fluid flow passages 12 and 13 are respectively communicated with at least one of the fluid throttles 14 and 15.
