Claim 11:
12. A magnetic sensor comprising:
a first magnetoresistive element configured to detect a magnetic field including a component in a first direction;
a second magnetoresistive element configured to detect a magnetic field including a component in a second direction; and
a coil that generates a coil magnetic field, the coil magnetic field being a magnetic field to be applied to the first and second magnetoresistive elements, wherein:
each of the first and second magnetoresistive elements includes a magnetization pinned layer having first magnetization whose direction is fixed and a free layer having second magnetization whose direction is changeable with the external magnetic field; and
the coil includes a conductor portion, the conductor portion extending in a third direction, the third direction being a direction intersecting each of a direction of the second magnetization of the free layer of the first magnetoresistive element when a strength of the component in the first direction of the magnetic field to be applied to the first magnetoresistive element is 0, and a direction of the second magnetization of the free layer of the second magnetoresistive element when a strength of the component in the second direction of the magnetic field to be applied to the second magnetoresistive element is 0.
