PURPOSE:To improve mass productivity and reliability by forming laminated films consisting of magnetic metallic material films or said films and insulator films on a nonmagnetic substrate, depositing glass for welding by evaporation further thereon, placing another sheet of nonmagnetic substrate further thereon and subjecting the substrates to high-temp. welding. CONSTITUTION:The laminated films consisting of the magnetic metallic materials 2 and the insulator films 3 are laminated on the nonmagnetic substrate 1a and the welding glass 5 is deposited on the laminated films and the substrate 1b. The substrates 1a, 1b are then subjected to the high-temp. welding by the welding glass 5 with the laminated films in-between. Plural pieces of the core half bodies cut to a prescribed size are arrayed on an L-shaped base and the gap surfaces 9 are polished. Gap materials are deposited on the polished surfaces. The other piece formed with a winding groove 7 and a cut groove 8 for glass is formed. These pieces are butted to each other and the low melting welding glass is disposed therebetween. Weight is applied to the pieces so that the substrates are welded at a high temp. The L-shaped base is removed and the part joined by the glass is cut to a prescribed size. A magnetic head having the high reliability is thus obtd. with the high mass productivity.
