PROBLEM TO BE SOLVED: To provide a wheel bearing with a sensor which is capable of compactly mounting the sensor for detecting load to a vehicle, sensing the load to a wheel, and reducing cost during mass production. SOLUTION: The wheel bearing in which a double-row roller 3 is intervened between the external member 1 and the internal member 2, is provided with the sensor unit 21. The sensor unit 21 is composed of the sensor fixing member 22 to be fixed on the internal peripheral surface of the external member 1 of the stationary side member, and the plurality of strain sensors 23 for measuring the strain of the sensor fixing member 22. The sensor fixing member 22 is provided with at least two contact fixing parts 22a and 22b for the external member 1, and between the adjacent contact fixing parts at least one notched part 24c is provided, and the strain sensor 23 is arranged in the notched part 24c. Between the two contact fixing parts 22a and 22b of the sensor fixing part 22 is formed by the two parallel plates 24 and circular arc plate 25 connecting both the plates.
