<P>PROBLEM TO BE SOLVED: To provide a low-cost bearing with a highly reliable sensor capable of accurately measuring a rotating state throughout a long period of time by preventing intrusion of foreign matter into a sensor part. Ž<P>SOLUTION: The bearing A with the sensor is equipped with a stationary ring 4 maintained in a non-rotating state, a rotating rotation ring 2 arranged facing the stationary ring, and the sensor 20 detecting a rotating state of the rotation ring. The sensor is equipped with a detecting reception object 22 rotating in the same rotating state as the rotation ring, and a detector 24 detecting the rotating state of the detecting reception object. A sensor housing 25 is provided comprising a housing body 26 housing the detector, and a housing cover 28 positioning the housing body 26. With respect to fixing the detecting reception object to the rotation ring and rotating it together, the detector is fixed to the stationary ring via the housing cover in a state of housing it in the housing body such that it can face the detecting reception object at a predetermined interval, an arranged side of the sensor is sealed by the detecting reception object and the sensor housing, and intrusion of foreign matter from a bearing exterior is prevented.
