PROBLEM TO BE SOLVED: To provide a laminate molding method, with which a multi-layered molding excellent in drape can be efficiently manufactured by a method wherein the sagging of an injected molten resin is eliminated and, at the same time, a skin material is prevented from being damaged in the neighborhood of a gate in a laminate molding method with a horizontal mold clamping type injection molding machine. SOLUTION: In a laminate molding method for fusingly integrating molten resin as a core material and the skin material with the horizontal mold clamping type injection molding machine, after the skin material is arranged in a mold and then the mold is closed so as to leave a predetermined value of mold clearance and, after that, the injection and filling of the molten resin is started and, after the elapse of a certain period of time after the starting of filling, the mold clearance is enlarged to a predetermined value and, after the completion of injection, the mold is clamped again.
