PROBLEM TO BE SOLVED: To provide a sensor-equipped bearing for a wheel capable of accurately detecting a load acting on the bearing for the wheel or on a tire tread, without receiving influence of a rolling element. SOLUTION: This bearing for the wheel is provided by interposing the rolling element 5 between rolling travel surfaces of mutually opposed double rows of an outer member 1 and an inner member 2. One or more of sensor units 20 are arranged in a fixed side member among the outer member 1 and the inner member 2. The sensor units 20 have a strain generating member having two or more of contact fixing parts fixed by contacting the fixed side member, and a sensor for detecting its strain. The sensor units 20 are arranged so that its strain generating member is positioned by slipping out of a line segment extending in the direction for forming a rolling body contact angle by passing through the center of the rolling element 5.
