Claim 17:
18. A magnetic sensor comprising a magnetoresistive element whose resistance changes with an external magnetic field, and a support member that supports the magnetoresistive element, wherein:
the magnetoresistive element includes a magnetic layer having a magnetization whose direction is variable depending on the external magnetic field;
the magnetic layer has a first surface having a shape that is long in one direction and a second surface located opposite the first surface;
the first surface has a first edge and a second edge located at both lateral ends of the first surface;
the support member has an opposed surface opposed to the magnetoresistive element;
at least a part of the opposed surface is inclined relative to a reference plane; and
an angle that the opposed surface forms with the reference plane in a given cross section intersecting the magnetic layer and perpendicular to a longitudinal direction of the first surface is greater at a first position that is a position on the opposed surface closest to the first edge than at a position on the opposed surface closest to a predetermined point on the first surface between the first edge and the second edge.
