There are provided a relative angle detection device suitable for expanding a torque detection range; and a torque sensor, an electric power steering device and a vehicle including the relative angle detection device. Based on a first sin signal representing sin(¸os+¸) and a first cos signal representing cos (¸os+¸) in accordance with a rotation angle(¸is) of a first multipolar ring magnet (10) that synchronously rotates with an input shaft(22a) from between the coaxially arranged input shaft(22a) and an output shaft(22b) and based on a second sin signal representing sin¸os and a second cos signal representing cos¸os in accordance with a rotation angle (¸os) of a second multipolar ring magnet(11) that synchronously rotates with the output shaft (22b), sin¸ and cos¸ are calculated in accordance with a relative angle (¸) between the input shaft (22a) and the output shaft(22b), and from ¸=arctan(sin¸/cos¸), the relative angle (¸) is calculated.
