Summary:PROBLEM TO BE SOLVED: To provide a foamed laminate having a good appearance and uniform cells. SOLUTION: The method of manufacturing a foamed laminate having a foamed layer and an nonfoamed layer adjacent to the foamed layer includes a process of extruding a resin composition A containing a foaming agent and a resin composition B from a die to form the foamed and nonfoamed layers. In the extrusion process, the temperature of the resin composition B is set to be higher than that of the resin composition A. COPYRIGHT: (C)2010,JPO&INPIT
