A magnetoresistive head has a magnetoresistive film including first and second magnetization free layers, an intermediate layer sandwiched between the first and second magnetization free layers, an underlayer and a protective layer, a first electrode, a second electrode, a pair of first antiferromagnetic films, and a pair of second antiferromagnetic films. The first electrode is connected with the underlayer and the second electrode is connected with the protective layer, the electrodes allowing a current to flow in a direction substantially perpendicular to the plane of the magnetoresistive film. The pair of first antiferromagnetic films imparts a magnetic bias to the first magnetization free layer in a predetermined direction, and the pair of second antiferromagnetic films imparts a magnetic bias to the second magnetization free layer in a predetermined direction.
