PROBLEM TO BE SOLVED: To provide an angle detector, a relative angle detector, a torque sensor, an electric power steering device, and a vehicle, with which it is possible to detect a rotation angle with high accuracy.SOLUTION: The angle detector includes a sensor unit for detecting the rotation angle of a rotor and outputting a sin signal and a cos signal, with at least one of the sin signal and the cos signal corrected on the basis of sensor correction information that is set in advance so as to ensure that the value of the sin signal outputted by the sensor unit in accordance with the rotation angle of the rotor is brought close to the reference sin signal value of rotation angle of the rotor, or the value of the cos signal outputted by the sensor unit in accordance with the rotation angle of the rotor is brought close to the reference cos signal value of rotation angle of the rotor.SELECTED DRAWING: Figure 21
