An angle sensor unit for measuring a rotational angle of a steering shaft may include a two-pole magnet that is disposed at one end of the steering shaft and has two poles that are opposite one another relative to a magnetic axis corresponding to a rotational axis of the steering shaft, two magnetic-field-direction-dependent magnetic field sensors assigned to the magnet and arranged with their sensitive sensor faces parallel to the external face of the magnet and at two different distances from the magnet and centers of the magnetic field sensors being located on the magnetic axis, and an evaluation unit configured to determine a rotational angle based on signals of the two magnetic field sensors and magnetic flux density, which is respectively present in a region of the two magnetic field sensors, of the magnetic field originating from the magnet.
