A quality control method for a constant velocity universal joint 13 includes a step of attaching an IC tag 9 to the constant velocity universal joint 13, a step of recording information in the IC tag 9 about the constant velocity universal joint 13, a utilizing step for reading the information recorded in the IC tag 9 at any arbitrarily chosen time. The IC tag 9 is attached to one of elements 2 such as an outer race 14, an inner race 15, an intermediate shaft 12 and boots 18, all forming respective parts of the constant velocity universal joint 13. This IC tag 9 is recorded with information on, for example, the manufacturing step, the identification number, the date of manufacture and/or the place of manufacture with respect to the elements 2 and the constant velocity universal joint 13.
