PURPOSE:To increase the joining force between an oxide and a metallic magnetic material and to improve the durability by providing a nonmagnetic field having good affinity to joining sides of both magnetic materials and joining them, and preventing those nonmagnetic films from residing nearby a front gap. CONSTITUTION:The oxide magnetic material 110 and metallic magnetic material 14 are adhered into a laminate across the 1st nonmagnetic films provided to the oxide magnetic material 110, e.g. glass thin films 13a and 13b and the 2nd nonmagnetic films 15a and 15b having good affinity with glass thin films 13a and 13b provided to the metallic magnetic material 14 to constitute a magnetic head 26 so that the 1st nonmagnetic films 13a and 13b and the 2nd nonmagnetic films 15a and 15b are not present nearby the front gap 27. Therefore, the nonmagnetic thin films 15a and 15b for adhesion like alumina films which react on the glass films 13a and 13b to produce bubbles easily are not present nearby the front gap 27, so the magnetic head 26 is never clogged and there is neither the astability of the output nor a decrease in performance. The nonmagnetic material 16 having high hardness is charged in the groove 12 of the magnetic body 110 to obtain wear resistance and improve the durability.
