Abstract
An angular position detecting apparatus using a magnetic detecting element, which can voluntary widely set an output change characteristic of the magnetic detecting element with respect to angular positions. An angular position detecting apparatus includes a cylindrical yoke, and a magnet fixed to a predetermined position in the cylindrical yoke. A magnetic detecting element, which is fixed to a rotor, is provided in a magnetic field generated between the magnet and the cylindrical yoke, so that a position of the magnetic detecting element is shifted from a rotation axis P of the rotor by a predetermined distance r. A ferromagnetic thin film magnetic resistance element applies a magnetic field which has intensity so that outputs from the elements are saturated. As a result, the magnetic detecting element generates outputs depending only on a magnetic flux detection angle &thgr;s independent of an influence of changes of magnetic field intensity due to temperature changes. In this case, when at least one of a rotation radius r of the magnetic detecting element and a radius R of the cylindrical yoke is voluntary determined, an output change characteristic of the magnetic detecting element can be voluntary set.
