Claim 8:
9. A magnetic sensor comprising a magnetoresistive element whose resistance changes with an external magnetic field, 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;
at least a part of the first surface is inclined relative to a reference plane so that an inclination angle is greater than 0, the inclination angle being an angle that the first surface forms with the reference plane; and
in a given cross section intersecting the magnetic layer and perpendicular to a longitudinal direction of the first surface, the inclination angle at the first edge is greater than the inclination angle at a predetermined point on the first surface between the first edge and the second edge.
