<p><P>PROBLEM TO BE SOLVED: To provide a foamed multilayer sheet having both of moisture permeability and contamination resistance (particularly in a venthole portion). <P>SOLUTION: The foamed multilayer sheet is obtained by layering a foamed resin layer, which is formed by a melt-molding method, and a surface protective layer in this order on a base material. Ventholes, each of which penetrates the surface protective layer and the foamed resin layer at the least, are formed on the foamed multilayer sheet, so that the foamed multilayer sheet has contamination resistance while ensuring moisture permeability. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
