<P>PROBLEM TO BE SOLVED: To provide a novel composite membrane composed of a moisture-permeable resin layer laminated on one side of a hydrophobic porous membrane, wherein the moisture-permeable resin layer is contained in a reinforcing porous membrane and the composite membrane has particularly a good steam separation property. <P>SOLUTION: The composite membrane is produced through lamination of a moisture-permeable resin layer to a side of a hydrophobic porous membrane that is produced by a method including applying a liquid containing the moisture-permeable resin to the reinforcing porous membrane or impregnating the reinforcing porous membrane with the liquid in advance, removing the solvent from the liquid by washing, drying, or the like, and then bonding the resultant material to the hydrophobic porous membrane by thermal compression, wherein the moisture-permeable resin layer is contained in the reinforcing porous membrane. <P>COPYRIGHT: (C)2013,JPO&INPIT |
