The problem to be solved is to provide an angular sensor where deterioration in detection accuracy or occurrence of erroneous detection due to influence of an external magnetic field is reduced. An angular sensor 1 which detects a rotation angle of an object includes a magnet 12 which is rotated according to the object and a magnetic sensor 11 which detects the rotation angle of the magnet based on a change in magnetic field generated by from magnet, wherein a direction of an external magnetic field which is a magnetic field other than the magnetic field of the magnet and a direction of the magnetic field generated by the magnet in a rotation range where the magnet is rotated are set to have an angle of less than 90 degrees. |
