PROBLEM TO BE SOLVED: To produce an electronic equipment housing made of a metal plate and a thermoplastic resin by composite molding by a method for manufacturing with a high productivity. SOLUTION: A laminating method has the steps of pretreating 102 such as degreasing, coating and conversion treating or the like a coil original plate 100 or a sheet original plate 101 in an original plate process, then coating the plate 100 or the plate 101 with an adhesive 103, laminating 105 a thermoplastic resin film 104 on its surface, thereby manufacturing a laminated original plate 106. Meanwhile, a precoating method has the steps of coating 109 the plate with a thermoplastic resin 108 in an original plate process, and baking the plate in an oven 110, thereby obtaining a precoated original plate 111. In a component processing step, the laminated original plate or the precoated original plate manufactured in the original plate process is metal press molded in a multi-cavity mold, thereby manufacturing a plurality of object metal components. Thus, an integrally efficient production of thermally welding of an in-mold resin to the coil original plate of multiple sizes or the sheet original plate, processing the pressed component from the original plate, and in-mold molding can be performed.
