A process for producing a multilayer molded article in which a surface of a thermoplastic resin substrate is partly or entirely laminated with a skin material. In the process, a mold including a pair of a female and a male mold halves is used, the process involves (a) supplying the skin material to a predetermined position between the female and the male mold halves in an open state; (b) supplying a molten thermoplastic resin between the skin material and a molding surface of any one of the female and the male mold halves; (c) clamping the mold after or while supplying the molten thermoplastic resin; (d) carrying out primary cooling of the molten thermoplastic resin in the mold; (e) moving a part or a whole of the mold half, wherein the part or the whole of the mold half has a molding surface contacting the skin material, relative to a surface of the skin material to make a gap between the surface of the skin material and a molding surface of the part or the whole of the mold half; (f) carrying out secondary cooling of the molten thermoplastic resin in the state of keeping the position of the mold halves made in the above (g); and (h) opening the mold halves after solidification of the molten thermoplastic resin and taking the molded article out of the mold.
