A pad bearing includes a pad disposed on a radially outer side of a rotary shaft and supporting the rotary shaft so as to be rotatable around an axis, a block-shaped nozzle member disposed on an upstream side with respect to the pad on the radially outer side of the rotary shaft and including a discharge hole for discharging a lubricant toward an outer peripheral surface of the rotary shaft, and a compressed flow forming unit disposed in at least one of the pad and the nozzle member and configured to compress a flow of the lubricant flowing along the outer peripheral surface of the rotary shaft as the rotary shaft rotates.
