PROBLEM TO BE SOLVED: To reduce a phase difference between A-phase/B-phase or A-phase and Za-phase/Zb-phase or Z-phase, and to miniaturize a magnetoresistance effect element small in size, thereby enhancing origin detection accuracy of a rotating body. SOLUTION: A magnetoresistance effect element 21 for detection of A-phase/B-phase or A-phase and a magnetoresistance effect element 22 for detection of Za-phase/Zb-phase or Z-phase are provided side by side in the same shape on the same substrate, and an arrangement direction with respect to a moving body is vertical to a moving direction of the moving body. An A-phase signal is output from a terminal electrode 21A at the middle point between a magnetoresistance effect element 21a and a magnetoresistance effect element 21b, and a B-phase signal is output from a terminal electrode 21B at the middle point between a magnetoresistance effect element 21c and a magnetoresistance effect element 21d. Further, a Za-phase signal is output from a terminal electrode 22A at the middle point between a magnetoresistance effect element 22a and a magnetoresistance effect element 22b, and a Zb-phase signal is output from a terminal electrode 22B at the middle point between a magnetoresistance effect element 22c and a magnetoresistance effect element 22d.
