[PROBLEMS] To provide a water-repellent porous silica film having uniform pores applicable to an optical functional material or an electronic functional material, a method for producing the same, and a use thereof. A silica skeleton in which a fluorine atom is immobilized by a covalent bond has an alkali metal content of 10 pp. A water-repellent porous silica film having uniform pores of b or less is synthesized. [Effect] It is possible to provide a water-repellent porous silica film having uniform pores, a method for producing the same, and a use thereof. |
