<P>PROBLEM TO BE SOLVED: To provide a sensor equipped bearing for a wheel capable of accurately detecting loads acting on the bearing and on the ground contact surface of a tire without being affected by rolling bodies. Ž<P>SOLUTION: The bearing for the wheel is formed by arranging rolling bodies 5 between double-row, opposed rolling surfaces of an outer member 1 and an inner member 2. A fixed-side member among the outer member 1 and the inner member 2 is provided with one or more sensor units 20. Each of the sensor units 20 is provided with a distortion generating member 21 having two or more contacting fixed sections which are in contact with and fixed to the fixed-side member, and also with a sensor 22 for detecting the distortion of the distortion generating member. The sensor units 20 are arranged such that each of the deforming members 21 thereof is located at a position so as to be offset from a line L passing through the center of each rolling body 5 and extending in the direction of forming a rolling body contact angle, and on an inboard side further from the rolling body 5 on the inboard side among the double-row rolling bodies.
