A simple circuit configuration without increasing the number of magnetic poles of a magnet can be performed and angular resolution can be improved. The polarities is determined and the absolute values are compared in accordance with the rotation angle of a magnet ( 1 ) based on sensor output signals a and b outputted from the magnetic sensors ( 2 ) and ( 3 ) to produce polarity determination signals c and d and absolute-value-comparison signals e, f, and g. The rotation angle of the magnet ( 1 ) is determined based on the polarity determination signals c and d and the absolute-value-comparison signals e, f, and g to output a determination result signal h.
