Zusammenfassung:A spin-valve magnetoresistive head having end parts of a free magnetic layer insensitive to an external magnetic field so as to improve sensitivity is provided. The spin-valve magnetoresistive head includes, at least on the terminal part sides, a lamination formed of a first antiferromagnetic layer, a soft magnetic layer, an antiparallel coupling intermediate layer, and a first free magnetic layer.
