[Purpose] ferromagnetic metal thin film or ferromagnetic or preventing the degeneration of an oxide, the glass flow and mitigation of internal stress to increase the adhesiveness thereof to the lead to an improved washing power reliability a magnetic head is intended to. [Configured] magnetic core half (10, 11) is consisting of an ferromagnetic, magnetic core half (10, 11) joining surfaces of ferromagnetic thin -23b1 ' paragraph wave grudge on an inclined road (10a, 11a) the ferromagnetic metal thin film (13) is formed is deposited, ferromagnetic metal thin film (13) the magnetic core half (10, 11) than the mold layer of magnetic gap forming face (14) to 80 to 20 are tilted at an angle, in addition ferromagnetic metal thin film (13) even polymerization of olefins in the presence of non-magnetic coating (15) is formed, magnetic gap g a side part of the oxide glass (16, 17) is melted, the. filled with an. [Effect] magnetic head in ferromagnetic oxide soft-magnetic enhanced properties which is made the second substrate is disposed from output function of foil, sputtering rates for a plate is installed on the lower plate relaxed, each [...] may be mitigated and a stress local, real estate, Galanin can be pad prevents the baggage.
