PURPOSE:To produce easily and inexpensively a magnetic head by the constitution consisting in removing an overcoat film of a magnetic head pad part by using a polyimide resin having <=15% rate of imide formation. CONSTITUTION:The photosensitive resin 3 is patterned to the pad part formed by laminating an electrode 1 on a substrate 2 and after the overcoat film 4 is formed thereon, the polyimide resin is dissolved away by a liftoff treatment to expose the pad part. Since the polyimide resin of <=15% rate of imide formation is used, the pad part is easily exposed and the easy production of the magnetic head is made possible.
