ABSTRACT:
An angular sensor which enables to obtain an output signal proportional to a relative rotational angle with low manufacturing cost and with miniaturized size. An angular sensor which includes a first magnet and a second magnet fixed to a rotation body, magnetic flux sensing surface is fixed to the stator to be positioned in magnetic field between the first magnet and the second magnet and perpendicular to magnetic sensing direction for sensing a magnetic flux, a magneto-electric transducer element for outputting an electric signal corresponding to a magnetic sensing direction element of the magnetic density, deflection yokes. The deflection yokes are positioned facing the magnetic flux sensing surfaces. The deflection yokes are positioned within a range of three quarters of a distance between the first magnet and the second magnet in X-axis direction and one half of a distance between the first magnet and the second magnet in Y-axis direction.
