<p>PROBLEM TO BE SOLVED: To obtain a dehumidifying film structure, in which water vapor can be selectively absorbed and through which water vapor can be passed, wherein moisture absorbing liquid can be held in a stable manner even in a dehumidifying operation under reduced pressure. SOLUTION: A layered structure consists of a porous film A impregnated with an absorbent liquid C and a hydrophobic porous film B adjacent to the film A. The film A is brought into contact with a gas containing water vapor, while the film B is brought into contact with a reduced pressure part to allow the water vapor to be selectively passed to the reduced pressure part through the layered film.</p> |
