PROBLEM TO BE SOLVED: To provide a magneto-resistance effect device having a good output characteristic and a high processing yield. SOLUTION: The magneto-resistance effect device comprises a magneto- resistance effect film 14 having a fixed magnetization layer wherein a direction of magnetization is essentially fixed in one direction, a free magnetization layer 15 wherein a direction of magnetization varies depending on a direction of an external magnetic field, and a non-magnetic layer interposed between the fixed magnetization layer and the free magnetization layer; a pair of bias films 28 which contains a hard magnetic material and is so positioned as to be apart from each other in a track width direction to apply a bias magnetic field to the magneto-resistance effect film; a pair of soft magnetic films 24 which is so disposed as to separate the magneto-resistance effect film from the bias film; and a pair of electrodes 10 and 16 which can supply a sense current in a direction nearly vertical to a film face of the magneto-resistance effect film.
