Summary:PROBLEM TO BE SOLVED: To provide a magnetic sensor capable of reading magnetism in the whole range of a detection range, heightening the magnetic pattern detection sensitivity even if a magnetic pattern array is changed, and preventing generation of a cross talk. SOLUTION: Element rows S1, S2 formed by arraying a plurality of magnetic resistance elements 3 along the crossing direction at a prescribed angle with the passing direction of an analyte 6 having the magnetic pattern 15 are installed in the shifted state in the passing direction of the analyte 6. Each magnetic resistance element 3 in one element row has an array form wherein its magnetic induction region 10 overlap that of the magnetic resistance element 3 in the other element row in the passing direction of the analyte 6 so that the whole region where the analyte 6 passes becomes the magnetic induction region in the array direction of the magnetic resistance elements 3.
