Abstract
A magnetic steering angle detection apparatus includes a magnet rotating in synchronization with a steering shaft mounted on a vehicle, senses a change of a magnetic field from the magnet by use of a hall IC mounted on a column side, and detects a rotation angle of the steering shaft. The magnet has S and N poles arranged on a plane of which normal line is in a substantially axial direction of the steering shaft. The hall IC is disposed such that a sensing direction of the hall IC is set to be a substantially single direction and the sensing direction is made to substantially coincide with the axial direction of the steering shaft.
