<P>PROBLEM TO BE SOLVED: To provide a runout measurement jig and a runout measurement method using the same capable of easily and inexpensively measuring the runout of each of a plurality of flange pieces. Ž<P>SOLUTION: A hub wheel 3 (rotating wheel) of a hub unit 1 (rolling bearing device) includes a wheel attachment flange 3c (flange). In the wheel attachment flange 3c, the plurality of flange pieces 13 including bolt insertion through-holes 3d for inserting bolts 6 therethrough are individually protruded to the outside in the radial direction of the hub wheel 3, and cutout parts 14 are formed between the flange pieces 13. The runout measurement jig 50 includes a plurality of measurement plates 51 which are mounted on the flange pieces 13, respectively, and in which the sides opposite the sides at the flange pieces 13 are provided as measurement surfaces 51b brought into contact with probes 61. When each measurement plate 51 is mounted on the flange piece 13, circumferential end faces 51a of the adjacent measurement plates 51 are brought into contact with each other, and the respective measurement surfaces 51b are continuous in a circular ring shape in plan view.
