Abstract: A rotation angle detection sensor includes a magnet body subjected to magnetization in an in-plane direction, a first Hall element and a second Hall element separated from each other and arranged offset to one of spaces divided by an imaginary plane including a rotation axis, and a third Hall element located in a position away from a straight line passing through the first Hall element and the second Hall element. A storage section stores a rotation angle that is related to electric signals having a phase difference therebetween, among electric signals of the first Hall element, the second Hall element, and the third Hall element. A detection section detects the electric signals of the first Hall element, the second Hall element, and the third Hall element and obtains from the storage section the rotation angle that is related to the detected electric signals.

Abstract: A grip, a magnet 140, and a substrate 150 are included. The grip is rotatable between positions where a throttle is fully closed and a position where the throttle is fully open with a rotating shaft as a center. The magnet 140 rotates integrally with the grip. The substrate 150 includes a plurality of Hall elements 165 and 175, and is fixed to face the magnet 140. The plurality of Hall elements 165 and 175 are disposed in such a way that magnetic flux densities different from each other are respectively applied to the plurality of Hall elements 165 and 175 when an external magnetic field acts in a state where the grip is located in the position where the throttle is fully closed.
