There is provided a machine component having an IC tag attached thereto, which can be controlled consistently from manufacture to disposal without the IC tag missed on the way. The machine component is embedded with the IC tag () made up of an IC chip having recorded thereon information unique to the relevant machine component and an antenna connected electrically with the IC chip.

A bearing with a rotational sensor has a magnetic sensor includes a race including an inner ring and an outer ring. Between the inner ring and the outer ring, a magnetic sensor holding member having an annular portion is arranged. The annular portion of the magnetic sensor holding member is provided with a holding portion holding the magnetic sensor. The magnetic sensor is held in the holding portion of the magnetic sensor holding member and is arranged between the outer circumferential surface of the inner ring and the inner circumferential surface of the outer ring. Therefore the bearing with a rotational sensor that is improved to allow easy assembly and compactness can be obtained.
