Abstract
A magnetoresistance element comprises one or more magnetoresistors whose resistances are varied with the change in magnitude of the magnetic field produced by a multipolar magnet disposed on a moving object. The magnetoresistors are provided adjacent to the object and arranged to have a sensitivity which is distributed along the moving direction of the object with a predetermined distribution breadth and which has one or more peak values, so as to provide an output a signal having a sinusoidal waveform.
