A rotation sensor-equipped bearing which can be assembled easily and has a reduced axial length and which, even if there is a change in the shape of the shaft, can be accommodated to the change by the change of a minimum number of parts. A rotation sensor- equipped bearing is provided with a rotation sensor (1) composed of an encoder (2) and a sensor section (3). A bearing (20) is provided to the inner periphery of a sensor housing (4) to which the sensor section (3) is mounted. The sensor section (3) is provided with a sensor mounting board (7) and a sensor (8) which is affixed to the sensor mounting board (7). A board fitting groove (10) which extends in the direction of a chord of a circular cross-section of the outer peripheral surface of the sensor housing (4) and which runs in the axial direction is provided to the sensor housing (4). The sensor section (3) is mounted to the sensor housing (4) by fitting the sensor mounting board (7) into the board fitting groove (10).
