Abstract
A thin film magnetic head 10 is comprised of a lower core 1b, a magnetic gap 2, a coil 4, an upper core 1a, a protective substrate 6, a first inorganic insulation film 3 and a substrate 7 on which the lower core, the magnetic gap, the coil, and the upper core are provided. The protective substrate is welded to the substrate by using a welding glass 5. A second inorganic insulation film 3b is additionally provided on the substrate so that the substrate is sandwitched between the first and second inorganic insulation films to prevent the substrate from warping when heated for welding.
