A magnetoresistive head includes a substrate, first and second magnetic shields, a magnetoresistive effect film formed within a gap layer between the first and second magnetic shields, a permanent magnet layer provided on both sides of the magnetoresistive effect film in order to apply a magnetic field to the film, and an electrode film provided on the permanent magnet layer so as to permit a signal detected current to flow, wherein a magnetic film is stacked on the permanent magnet layer with a nonmagnetic separation layer interposed between the permanent magnet layer and the magnetic film so that the magnetic film has formed therein a magnetic path, thus, it is possible to provide a GMR reproduce head of which the reproduction sensitivity can be maintained high even if the track width is narrow.
