To provide a wheel bearing with a sensor capable of compactly mounting the sensor for load detection on a vehicle, sensitively detecting the load on a wheel and reducing costs in mass-production.
In the wheel bearing for freely rotatably supporting a wheel to a vehicle body by interposing double-row rolling elements 3 between an outer member 1 and an inner member 2, a sensor unit 21 is mounted in a fixed side member of the outer member 1 and inner member 2. When the outer member 1 is taken as the fixed side member, for instance, the sensor unit 21 consists of a sensor mounting member 22 and one or more distortion sensor 23 mounted in the sensor mounting part 22. The outer member 1 includes a notch 17 in a part of a knuckle contact part 1a coming into contact with a knuckle 16.
