    摘要: A thin film magnetic head comprises an upper magnetic film and a lower magnetic film which cooperate to constitute a magnetic circuit including a magnetic gap, and a coil conductor film constituting a coil having a predetermined number of turns and extending between the upper and the lower magnetic films to intersect the magnetic circuit. The upper magnetic film is composed of a laminate constituted by magnetic thin film layers and non-magnetic thin film layers stacked alternately with each other. An electrically insulating layer formed of a photo-sensitive resin is interposed between the upper magnetic film and the coil conductor film.
