To provide an angle detection device and a relative angle detection device each of which can detect an angle with a higher degree of accuracy, and a torque sensor, an electric power steering device and a vehicle.SOLUTION: The angle detection device comprises: a first shaft; a first multipolar magnet; a first magnet sensor; a second magnet sensor; and an angle correction unit. The first magnet sensor can output a first distance correlation value in accordance with a first distance to the first multipolar magnet, and the second magnet sensor can output a second distance correlation value in accordance with a second distance to the first multipolar magnet. The angle correction unit calculates a first correction angle of the first multipolar magnet on the basis of a first angle detected by the first magnet sensor in accordance with rotation of the first multipolar magnet, the first distance correlation value, a second angle detected by the second magnet sensor in accordance with the rotation of the first multipolar magnet, and the second distance correlation value.SELECTED DRAWING: Figure 9
