Zusammenfassung:	PURPOSE:To provide a device for mounting a semiconductor element having stepped parts by a general plating method without needing a high positioning accuracy. CONSTITUTION:In a method of manufacturing a device for semiconductor element mounting use of a structure, wherein while a recessed part 10 with the flat bottom is formed at a prescribed position, a plurality of sheets of organic substrates, each formed with a wiring, are laminated to form a multilayer wiring board having stepped parts, through holes 9 are formed at arbitrary places other than the place of the recessed part 10 and a plating is applied to the holes 9, the organic substrates (polyimide resin glass-cloth base material copper-clad laminates) 4 and 4' are laminated and thereafter, the outermost side of the multilayer wiring board is covered with chemical-resistant resin films 1 and 1', then, the through holes 9 are formed and after a plated film 8 is formed on the sidewalls of the holes 9, the films 1 and 1' are peeled from the outermost side.
