Abstract

To provide a low refractive index film-forming composition for forming a low refractive index film which has a low refractive index, produces a strong antireflection effect, exhibits excellent adhesiveness with respect to a substrate, and is excellent in water repellency or antifouling properties of the coat surface; a production method of the composition; and a method for forming a low refractive index film. The low refractive index film-forming composition is prepared by generating a hydrolysate of (A) a silicon alkoxide by mixing the (A) silicon alkoxide with (B) water, (C) an inorganic acid or an organic acid, and (D) an organic solvent at a predetermined ratio, and mixing the hydrolysate with (E) silica sol, which is obtained by dispersing fumed silica particles in a liquid medium, at a predetermined ratio.
