In a magnetoresistive head, a magnetoresistive layer (6) detects a magnetic field signal from a magnetic recording medium on the basis of resistance changes, a soft magnetic bias layer (4) applies a transverse bias magnetic field to the magnetoresistive layer (6), a longitudinal bias layer (7) applies a longitudinal bias magnetic field to the magnetoresistive layer, a lead layer (8) supplies a sense current to the magnetoresistive layer (6). The soft magnetic bias layer (4) is made of a material having a transverse uni-axial anisotropy field, and the magnitude of the anisotropy field is below 20 [Oe].
