PROBLEM TO BE SOLVED: To provide a magnetoresistive magnetic head, capable of showing an excellent reproducing waveform by applying a desired bias magnetic field to a MR element. SOLUTION: The magnetoresistive magnetic head provided with a magnetoresistive element, having a prescribed thickness and a generally rectangular principal surface and adopting an end face as an external magnetic field detecting face and a pair of vertical bias layers, disposed so as to sandwiching the magnetoresistive element and applying the bias magnetic field in the longitudinal direction of the magnetoresistive element is characterized in that in the pair of vertical bias layers, each part being flush with a face other than the external magnetic field detecting face of the magnetoresistive element is set with a length of 1.5μm or higher.
