Abstract
In a position detecting apparatusof the present invention, magnetic resistance circuits A and B of a first main circuitinclude a reference magnetic resistance element +A, an even harmonic correction magnetic resistance element +Abeing placed at a position shifted by (1/4)λ or (3/4)λ from the reference magnetic resistance element +A, with respect to a reference wave, and a third harmonic correction magnetic resistance element +Abeing placed at a position shifted by (1/6)λ from the reference magnetic resistance element, with respect to a reference wave, and magnetic resistance circuits A' and B′ of a second main circuitinclude the magnetic resistance circuit of the second main circuitincludes a reference magnetic resistance element +A′a fifth harmonic correction magnetic resistance element +A′being placed at a position shifted by (1/10)λ from the adjacent magnetic resistance element, with respect to a reference wave and a fifth harmonic correction magnetic resistance element +A′being placed at a position shifted by (4/15)λ from the reference magnetic resistance element +A′with respect to a third harmonic wave.
