The object of the present invention is to provide a hydrodynamic bearing, a method for manufacturing the same, and a spindle motor, with which the gap in the axial direction required for the smooth operation of a bearing can be sufficiently ensured. A method for manufacturing a hydrodynamic bearing comprising a shaft 7, a sleeve 8 attached so as to be capable of relative rotation with respect to the shaft 7, a first flange unit 6 fixed to or integrated with the shaft 7, and a second flange unit 9 fixed to the shaft 7, the method comprising at least inserting the shaft 7 into the sleeve 8, and inserting the shaft 7 into the second flange unit 9, pressing the top face of the second flange unit 9 in the axial direction, and fixing the second flange unit 9 to the shaft 7 by welding the shaft 7 and the second flange unit 9 while maintaining the pressing state.
