MAGNETIC SENSOR

PROBLEM TO BE SOLVED: To provide a magnetic sensor improved in resistance to an external magnetic field.SOLUTION: A first bias layer 10 and a second bias layer 11 are disposed on both sides along a direction X of a first element part 9A. The bias layers 10 and 11 are magnetized along a direction Y1. The first element part 9A is supplied with a bias magnetic field B1 along a direction X1. A first soft magnetic material 12a is disposed in a center portion of the first bias layer 10, a second soft magnetic material 12b is disposed in a center portion of the second bias layer 11, and the soft magnetic materials 12a and 12b are provided on both sides along a direction Y of the first element part 9A to be shifted from each other along the direction X. A third soft magnetic material 12c is disposed on a side of the second soft magnetic material 12a opposite to a side thereof opposing the first soft magnetic material 12a. The first soft magnetic material 12a and the third soft magnetic material 12c have ends in the same positions along the direction Y. A distance T1 between the first soft magnetic material and the second soft magnetic material is the same as a distance T2 between the second soft magnetic material and the third soft magnetic material.
