PROBLEM TO BE SOLVED: To provide an angle sensor suitable for suppressing the influence of magnetic flux variation on the angular error, and provide a torque sensor, electric power steering device, transmission, and vehicle that include the angle sensor.SOLUTION: The angle sensor includes: a cylindrical multipolar ring magnet 10 circumferentially magnetized by sine wave magnetization; a first magnetism collecting yoke 11 arranged so as to face the outer peripheral surface of the multipolar ring magnet 10 and have a phase difference in the circumferential direction; a second magnetism collecting yoke 12; a magnetic detector for detecting a magnetic flux collected by the first and second magnetism collecting yokes 11 and 12; and an angle calculation circuit for calculating the rotation angle of the multipolar ring magnet 10 on the basis of the magnetic flux detected by the magnetic detector.SELECTED DRAWING: Figure 3
