A magnetoresistive element has a magnetization pinned layer including a magnetic film a magnetization direction of which is substantially pinned in one direction, a magnetization free layer including a magnetic film a magnetization direction of which is varied depending on an external magnetic field, a composite spacer layer interposed between the magnetization pinned layer and the magnetization free layer, and including an insulating portion and a magnetic metal portion, and a pair of electrodes configured to supply a sense current in a direction perpendicular to planes of the magnetization pinned layer, the composite spacer layer and the magnetization free layer, in which the magnetic film included in the magnetization pinned layer and being in contact with the composite spacer layer has a bcc structure.
