PROBLEM TO BE SOLVED: To provide a sensor pattern arrangement structure of a magnetic sensor capable of inhibiting variations of an offset voltage, and a manufacturing method thereof. SOLUTION: A surface of a substrate 2 includes a plurality of sensor patterns 10 (two of 10a and 10b in this example) having sensor elements assembled in a bridge-like manner (Wheatstone bridge). A first sensor pattern 10a includes magnetic resistances 11 to 14. A second sensor pattern 10b includes magnetic resistances 21 to 24. The magnetic sensor 1 in this embodiment has all reference lines Ka1 to Ka4 and Kb1 to Kb4 of the magnetic resistances 11 to 14 and 21 to 24 obliquely arranged to central lines La and Lb of the substrate 2.
