Title: MAGNETIC RESISTANCE ELEMENT AND ITS MANUFACTURING METHOD, AND MAGNETIC SENSOR USING THE MAGNETIC RESISTANCE ELEMENT
Abstract:
The present invention provides a high-sensitivity magnetic resistance element and a magnetic sensor which are superior in durability and reliability and used for a magnetic encoder or the like, and their manufacturing method. The magnetic resistance element of the present invention is characterized in that the ferromagnetic thin film is covered with a double protective film having a specific composition. The magnetic sensor of the present invention is characterized by the above magnetic resistance element incorporated therein and a protective film at the sliding portion with a magnetic medium. The method for manufacturing the magnetic sensor of the present invention is characterized by using a special jig which allows leads to accurately connect with the above magnetic resistance element.
