Abstract: A magnetic sensor includes a non-bias structure element section that has a laminated structure in which a fixed magnetic layer, a non-magnetic material layer, a free magnetic layer, and a protection layer are laminated, and that is extended in an X1-X2 direction; and soft magnetic bodies that are arranged on the element section in a contactless manner. The soft magnetic bodies include a first section, a second section, and a third section. The second section is located on a Y2 side of the element section and the third section is located on a Y1 side thereof. The second section of one of soft magnetic bodies faces the third section of the other soft magnetic body in a Y1-Y2 direction through the element section. An electrode layer is provided on the element section which faces the joint sections of the second section and the third section in the Y1-Y2 direction.

Abstract: A magnetic sensor includes a plurality of magnetoresistive elements that are formed by stacking a magnetic layer and a non-magnetic layer on a substrate and that exhibit a magnetoresistive effect and a soft magnetic member that converts a vertical magnetic field component into a horizontal magnetic field component. The soft magnetic member is formed of a plurality of first and second soft magnetic portions respectively extending in an X1-X2 direction and a Y1-Y2 direction, combined together in the shape of a lattice. The magnetoresistive elements have a sensitivity direction in the Y2 direction and include a magnetoresistive element located on a Y1 side portion side of the first soft magnetic portion and a magnetoresistive element located on a Y2 side portion side of the first soft magnetic portion, respectively receiving horizontal magnetic field components from the Y1 direction and Y2 direction.
