PROBLEM TO BE SOLVED: To provide a molding method for obtaining a molded article having a multilayered structure more excellent in interlaminar adhesion than that obtained by a conventional sheet insert molding method and capable of corresponding even to the point at issue of appearance. SOLUTION: In a molding method for obtaining the molded article having the multilayered structure by a sandwich molding method of a thermoplastic resin, (1) a thermoplastic resin sheet forming a sheet layer is preliminarily mounted on the surface of the cavity of a mold and/or the surface of the core of the mold and (2) a thermoplastic resin forming a skin layer and a thermoplastic resin forming a core layer are charged in the cavity of the mold having the sheet mounted therein under such a condition that the injection speed of the thermoplastic resin forming the core layer becomes 300 mm/sec or more to obtain the molded article having the multilayered structure having the sheet layer, the skin layer and the core layer.
