Abstract

有機溶媒、高分子化合物、及び前記高分子化合物に対して０．０１重量％以上５０重量％以下の可塑剤（ＴＰＰやＢＤＰなど）を含む溶液（１１）をエンドレスベルト（５１）にキャストする。キャストされた溶液（１１）は、キャスト膜（２２）となる。結露により、第１エリア（４６）を通過するキャスト膜（２２）上に水滴が形成する。第２エリア（４７）を通過するキャスト膜（２２）上の水滴が成長するとともに、有機溶媒が蒸発する。第３エリア（４８）を通過するキャスト膜（２２）上の水滴が蒸発する。剥取ローラ（５７）により、第３エリア（４８）を経たキャスト膜（２２）は、柔軟性に富む多孔フイルム（１７）としてエンドレスベルト（５１）から剥ぎ取られる。
