<p>A magnetic sensor includes a non-bias structured element section (9) that has a laminated structure in which a fixed magnetic layer (61), a non-magnetic material layer (62), a free magnetic layer (63), and a protection layer (64) are laminated, and that is extended in an X1-X2 direction; and a plurality of soft magnetic bodies (12,14) that are arranged on the element section (9) in a contactless manner. Each of the soft magnetic bodies (12,14) includes a first section (12e,14e), a second section (12f), and a third section (12g). The second section (12f) is located on a Y2 side of the element section (9) and the third section (12g) is located on a Y1 side of the element section (9). The second section (12f) of one of adjacent soft magnetic bodies (12,14) faces the third section (12g) of the other soft magnetic body (12, 14) in a Y1-Y2 direction through the element section (9). An electrode layer (16) which biases current is provided on the element section (9) which faces the joint sections (12f1,12g1) of the second section (12f) and the third section (12g) in the Y1-Y2 direction.</p> |
