The object of the present invention is to provide a magnetoresistive magnetic head having good, stable playback characteristics. In an MR head wherein an MR element is interposed between a lower shield layer and an upper shield layer, separated by non-magnetic layers. The lower shield layer and the upper shield layer are formed from a material having high permeability and high resistivity. Since the magnetic shield layers are formed from materials having high permeability and high resistivity, even if friction causes dragging of the head surface, there is effectively no short circuit between the magnetic shield layer and the magnetic element.
