摘要:
A surfactant is added to a polymer solution (21) which is a coating fluid comprising an organic solvent and a polymer. The surfactant contains a fluorine atom and reduces the surface tension of the coating fluid. The coating fluid (21) is applied to a casting band (26) as a support. Dew condensation is caused to occur on the surface of the polymer film (40) formed by coating fluid application. The organic solvent and droplets are vaporized to thereby cause droplets to come into the film and form voids. By the use of the polymer solution (21), which comprises a mixture of an organic solvent, a polymer, and a fluorine-atom-containing surfactant for surface tension reduction, a structure having such fine pores is formed and a film (12) of a honeycomb structure is obtained. This film is reduced in the adhesion of dust, etc. and has an even micropore structure
