Abstract: A method for producing a laminated material including a lower layer of highly-expanded plasticized polyvinyl chloride with cross-linking and a surface layer of thermoplastic resin sheet laminated on an upper surface of said lower layer, said method including the steps of: heating and kneading raw materials for the lower layer in an extruder, the raw materials excluding a cross-linking agent and a blowing agent; adding the cross-linking agent and the blowing agent; heating and kneading the obtained material at or less than a reacting temperature of the cross-linking agent and a decomposition temperature of the blowing agent to obtain a sheet; heating the sheet to cross-link and expand the sheet to form the lower layer of cross-linked highly-expanded plasticized polyvinyl chloride; and laminating the surface layer of the thermoplastic resin on the upper surface of the lower layer.
