Conventional coating liquids for forming porous silica have such a problem that porous silica films formed therefrom may have poor regularity in micropore alignment when the shelf life of the coating liquids are long. On the contrary, the coating liquid for forming porous silica of the present invention is excellent in self-life stability. Namely, the quality of porous silica formed therefrom is hardly affected by the length of self-life period of the coating liquid.
