Abstract
There is provided a magnetoresistive film high in resistance to destruction. The magnetoresistive film is a multilayered film including: an antiferromagnetic layer for generating a bias magnetic field; a pinned magnetic layer having magnetization whose direction is fixed by the bias magnetic field; a free magnetic layer having magnetization whose direction changes in accordance with an external magnetic field; and a nonmagnetic middle layer held between the pinned magnetic layer and the free magnetic layer, and is held by a pair of insulation layers (not shown). When a current is passed parallel to the magnetoresistive film, a current center as a position of the thickness direction for dividing the current into two so as to obtain respective equal current amounts is positioned on a side including the pinned magnetic layer during dividing of the magnetoresistive film into two in a center position of a layer thickness of the nonmagnetic middle layer in the thickness direction.
