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 plurality of resistor sections each including a plurality of MR elements, and a plurality of protruding surfaces each structured to cause the plurality of MR elements to detect a specific component of a target magnetic field. The plurality of MR elements are disposed dividedly in first to fourth areas corresponding respectively to the plurality of resistor sections. The plurality of protruding surfaces include a structural body extending across at least two of the first to fourth areas.
