Abstract
The magnetic sensor according to the present invention includes: a magneto-resistive effect element which has a stacked body in which a magnetization-free layer, a nonmagnetic layer, and a magnetization fixed layer are stacked in this order, and the longitudinal direction of which is a direction perpendicular to the stacking direction; and a current path layer which is provided on the magneto-resistive effect element via an insulation layer so as to be spaced apart from the magneto-resistive effect element in the stacking direction, and which generates a magnetic field by being supplied with a current. The current path layer extends in a direction which forms an angle between 0 and 45 degrees to the longitudinal direction of the magneto-resistive effect element when viewed from the stacking direction.
