PROBLEM TO BE SOLVED: To provide a bearing with a rotation sensor capable of detecting an absolute angle with high accuracy without performing the correction work after being assembled in a bearing mounting device. SOLUTION: This bearing device with the absolute angle sensor comprises a bearing 1 with a sensor, and a component 20 with a correction data recording part. The bearing 1 with the sensor has a rotation detector 6 performing two analogue outputs X, Y having 90°phase difference of an electric angle, as the detection outputs of the rotating angle to a fixed-side bearing ring, of a rotating-side bearing ring. In the component 20 with the correction data recording part, the correction data for correcting the error in operating the absolute angle of the rotating angle of the rotating-side bearing ring on the basis of two analogue outputs X, Y, is recorded, and the component 20 is paired with the bearing 1 with the sensor.
