摘要：
A solution (11) containing an organic solvent, a polymer and a plasticizer (TPP, BDP or the like) which is not less than 0.01 wt.% and not more than 50 wt.% of the polymer is cast onto an endless belt (51) to be a casting film (22). Water vapor is condensed from ambient gas on a surface of the casting film (22) passing through a first area (46) to form water drops. The water drops on the casting film (22) passing through a second area (47) are grown and the organic solvent thereof is evaporated. The water drops on the casting film (22) passing through a third area (48) are evaporated. The casting film (22) after passing through the third area (48) is peeled from the endless belt (51) as a flexible porous film (17) by a peel roller (57).
