PROBLEM TO BE SOLVED: To provide a bearing device for a wheel with face deflection accuracy of a flange side face improved as much as possible by preventing the flange side face from deforming due to hub bolt pressure-fit, and its manufacturing method. SOLUTION: Before a hub bolt is pressure-fit in a wheel mounting flange 4, an outer periphery of a small-diameter step part 2b formed on an outer periphery of a hub wheel 2 is supported by a supporting tool 13, and an end face 12 of the small-diameter step part 2b is adsorbed on a backing plate 15. The hub wheel 2 is rotated under a condition that a dummy bolt 16 having a predetermined tightening margin is pressure-fit into a bolt hole 11 formed on the wheel mounting flange 4, so that the flange side face 12 is ground by a cutting tool 18.
