PROBLEM TO BE SOLVED: To provide a molding method which enables the manufacture of a molded product having a three-dimensional shape and a concave-convex pattern on the surface. SOLUTION: The laminated sheet for thermoforming is thermoformed comprising: a thermoplastic film layer; an adhesive layer; and a supporting substrate layer whose surface of the side contacting the adhesive layer is smooth and which keeps opposite surface of the side a concave-convex pattern transferred by an embossing roll, laminated in this order. When the thermoforming of the sheet is carried out to the three-dimensional shape using a usual smooth mold, the molded product in which the concave-convex pattern formed on the external surface (rear face) of the side of the supporting substrate layer of the laminated sheet for thermoforming is embossed on the external surface (front face) of the side of the thermoplastic film layer and the concave-convex pattern attached to the supporting substrate layer exists clearly on the side of the thermoplastic film layer can be manufactured.
