PROBLEM TO BE SOLVED: To provide a magnetic detecting body capable of making the cycle of an output signal small with a relatively simple circuit constitution without incurring complexity concering works and the raising of the cost. SOLUTION: This magnetic detecting body is provided with two magneto resistance elements 6A, 6B detecting the relative displacement of the arrangement direction (x) of magnetic scales with respect to a magnetic member 1 having the magnetic scales 4 arranged with a constant set intervalλand, in the body, the elements are constituted so that the middle point potential Vo of both elements is taken out as an output and, also, both magnetro resistance elements 6A, 6B respectively have (m) pieces ((m) is an integer of >=2) of magnetic resistance paths 7A1, 7A2, 7B1, 7B2, and these paths are arranged so that an AC signal having the cycleλo of the 2 m multiple of the set intervalλis taken out.
