PROBLEM TO BE SOLVED: To provide a wheel bearing with a sensor which is capable of compactly mounting the sensor for detecting load on a vehicle, sensitively sensing the load on 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 weak part provided near the end part 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 to the external member 1, and between the adjacent contact fixing parts at least one notch 22c is provided, and the strain sensor 23 is arranged in the notch 22c. Further more, if the internal member 2 is the stationary side member, the fixing member 22 is fixed on the internal member 2. COPYRIGHT: (C)2007,JPO&INPIT
