Abstract
The problem to be overcome by the present disclosure is to reduce harmonic components included in output signals. A magnetic sensor includes a detecting magnetoresistance element and a canceling magnetoresistance element. A tilt angle formed by a magnetic sensing direction of the canceling magnetoresistance element with respect to a magnetic sensing direction of the detecting magnetoresistance element falls within a predetermined range. The predetermined range is defined by reference to either n×α/3 or n×α/3+α/2, where α is an angle of rotation of a rotator corresponding to one cycle of a fundamental harmonic included in output signals of the detecting magnetoresistance element and n is a natural number equal to or greater than 1.
