An magnetoresistive element includes: an underlayer made of a nitride; a pinning layer made of an antiferromagnetic layer overlaid on the underlayer, the pinning layer having the close-packed surface in the (111) surface of crystal, the pinning layer setting the (002) surface of crystal in parallel with the surface of the underlayer; a reference layer overlaid on the pinning layer, the reference layer having the magnetization fixed in a predetermined direction based on the exchange coupling with the pinning layer; a nonmagnetic layer overlaid on the reference layer, the nonmagnetic layer made of a nonmagnetic material; and a free layer overlaid on the nonmagnetic layer, the free layer made of a ferromagnetic material, the free layer enabling a change in the direction of the magnetization under the influence of an external magnetic field.
