PROBLEM TO BE SOLVED: To provide a bearing with a sensor to precisely measure the rotation state for the long term without damaging a body to be detected and a detecting body. SOLUTION: The bearing A with the sensor comprises a pair of rotary ring 2 and static ring 4 arranged to be relatively rotatable and oppositely to each other, and the sensor 20 to measure the rotation state of the bearing. The sensor comprises the body 22 to be detected rotating in the same rotation state as the rotary ring, the detecting body 24 to detect the rotation state of the body to be detected, and a sensor housing 26 to store the detecting body. The body to be detected is fixed to the rotary ring and is rotated together with the rotary ring, while the detection body is fixed to the static ring, being stored in the sensor housing so that it is spaced oppositely to the body to be detected at a predetermined interval, and there is provided a member 40 for preventing a foreign material from entering in order to prevent the foreign material from entering the opposite portion of the body to be detected and the detection body.
