。[Claim for Utility Model Registration] A lower magnetic pole core, a gap, an insulating layer containing a winding coil, and an upper magnetic pole core are laminated in this order by photolithography on a slider formed of an insulating substrate. The magnetic recording medium is magnetized by generating an electromagnetic field with a signal current flowing through the winding coil while sliding the slider on a slider floating surface above the magnetic recording medium to magnetize the magnetic recording medium and perform magnetic recording. In a thin-film magnetic head that reproduces recording by converting a magnetic field generated by a magnetized magnetic recording medium into a signal current using the winding coil, the head element is inclined with respect to the slider floating surface, and the upper magnetic pole A thin film magnetic head characterized in that the tip of the core and the tip of the lower magnetic pole core make the same angle with respect to the slider floating surface.
