PROBLEM TO BE SOLVED: To provide a magnetic sensor capable of high-sensitivity and high-accuracy evaluation of the strength of unidirectional magnetic field, even between narrow magnetic poles, using an MR element without having to make its constitution complex. SOLUTION: The magnetic sensor 1 is provided with the MR element 10 and a lead substrate 20 which holds the MR element 10 and in which a lead wiring 21 is printed, and a holding means 40 for tilting an element substrate surface P2 of the MR element 10 at a prescribed angle to a direction of magnetic field to be measured Mx. The holding means 40 is a wedge-shaped spacer member 40, interposed in between an element substrate 11 and the lead substrate 21. By appropriately setting the height of the spacer member 40, the MR element substrate surface P2 can be held at a prescribed tilt angle. COPYRIGHT: (C)2009,JPO&INPIT
