PROBLEM TO BE SOLVED: To provide a wheel bearing with a sensor wherein a load detecting sensor and a sensor signal processing circuit for processing the output of the sensor can be compactly installed in a vehicle for detecting a load on the vehicle with high sensitivity while effectively utilizing the output of the sensor for the vehicle control of an automobile and reducing cost at mass production. SOLUTION: The wheel bearing comprises an outward member 1 and an inward member 2, and double-row rolling elements 3 laid therebetween. A sensor unit 21 is mounted to a fixed side member out of the outward member 1 and the inward member 2. The sensor nit 21 is composed of a sensor mounting member 22, and at least one distortion sensor 23 mounted to the sensor mounting member 22. On the sensor mounting member 22, the sensor signal processing circuit 60 is provided for processing an output signal from the distortion sensor 23. COPYRIGHT: (C)2008,JPO&INPIT
