PROBLEM TO BE SOLVED: To provide a fluid bearing device and a lubricant filling method for the same capable of preventing the leakage of lubricant to the outside even in high-speed rotation, dispensing with wiping-out of the lubricant attached to an upper face at an opening part side of a sleeve and its neighborhood after the filling operation of the lubricant in a lubricant filling process, and free from the impairing of an oil repellent function. SOLUTION: An oil repellent agent coating face 20 on which an oil repellent agent 13 repelling the lubricant 5 is applied, is formed on the upper face 1a at the opening part side of the sleeve 1, and the oil repellent agent coating face 20 is inclined to allow the lubricant 5 on the oil repellent agent coating face 20 coated with the oil repellent agent 13, to be sucked and dropped to a clearance between the sleeve 1 and a shaft 4 . By filling the lubricant 5 by applying this constitution, the lubricant 5 placed on the oil repellent agent coating face 20 flows down onto the oil repellent agent 13 of the oil repellent agent coating face 20 and flows down to the clearance between the sleeve 1 and the shaft 4, as a result, which dispenses with the wiping-out work of the lubricant 5.
