<p>This rotation angle detector is provided with a rotating body having N poles and S poles alternatingly magnetized along a peripheral face at a magnetization width lambda, and first and second magnetic detectors for sensing a magnetic field generated by the rotating body. The first magnetic detector and second magnetic detector are set apart by a distance L. The first and second magnetic detectors, which are connected in series, are arranged between a first reference potential and a second reference potential. A signal corresponding to the rotation angle of the rotating body is outputted on the basis of the midpoint potential of the first magnetic detector and second magnetic detector, and the relation L=2lambda/n (where n is an integer greater than or equal to 2) is satisfied.</p> |
