PURPOSE:To provide a multiplayer foamed sheet in which a foamed sheet is disposed on a surface, a feel of softness is exhibited and utilization is increased in the sheet by a coextruding method. CONSTITUTION:A multilayer foamed sheet is formed by simultaneously extruding by a coextrusion and bringing a finely foamed sheet 2 into contact with at least one surface of a highly foamed sheet 1. A nonfoamed sheet 3 may be brought into contact with an opposite surface to a surface in contact with the sheet 2. An expansion ratio of the sheet 1 is preferably 1.2-5 times, and an expansion ratio of the sheet 2 is preferably 1.01-1.1 times. |
