Abstract
A magneto-resistive magnetic sensor has an overlay-type structure and includes a cap layer on a top surface of a magneto-resistive structure and a pair of electrodes provided on said cap layer with a separation from each other, wherein there is interposed an oxidation-resistant conductive film underneath each electrode, such that the oxidation-resistant conductive film is sandwiched between the cap film and the electrode.
