Provided is an angular sensor having less detection accuracy deterioration or false detection due to influence of external magnetic fields. An angular sensor (1) that detects the rotation angle of an object has: a magnet (12) that rotates corresponding to the object; and a magnetic sensor (11) that detects the rotation angle of the magnet on the basis of a change of a magnetic field generated from the magnet. The angular sensor is set such that an angle formed between the direction of external magnetic fields, i.e., magnetic fields excluding the magnetic field of the magnet, and the direction of a magnetic field generated within a rotation range, in which the magnet rotates, is less than 90 degrees. |
