Abstract: A magnetic sensor includes a plurality of MR elements, a plurality of yokes each including a portion long in a first direction, and a plurality of shields each including a portion long in a second direction. The plurality of MR elements include a plurality of first specific elements. The plurality of yokes include a plurality of yoke pairs each including one of the plurality of first specific elements. The plurality of shields include a plurality of shield pairs each with one of the plurality of first specific elements therebetween. The plurality of first specific elements are arranged in a direction intersecting both the first direction and the second direction.

Abstract: A magnetic sensor includes an insulating layer including a flat portion and a protruding portion, a first MR element, and a second MR element. The protruding portion includes a first inclined surface and a second inclined surface. The first MR element is disposed on the first inclined surface. The second MR element is disposed on the second inclined surface. The protruding portion extends in a first direction parallel to a top surface of a substrate, and includes a plurality of recess portions each recessed in a direction parallel to the top surface of the substrate at an end of the protruding portion in the first direction.

Abstract: A magnetic sensor includes a soft magnetic body having a first end surface and a second end surface located on opposite sides, a first MR element located near the first end surface, a second MR element located near the second end surface, and a first lead that electrically connects the first MR element and the second MR element and includes a portion overlapping the soft magnetic body when observed in a second direction orthogonal to a first direction in which the first and second MR elements are arranged.
