PROBLEM TO BE SOLVED: To provide a method for manufacturing a self-supported glass film without needing prolonged drying by using a sol-gel method and also hardly causing the crack or the deformation due to shrinkage. SOLUTION: The method for manufacturing the self-supported glass film comprises a step of by mixing a colloidal silica sol adjusted to≤pH4, a zirconium-containing compound, a binder and a crosslinking agent able to be crosslinked with the binder at≤50°C to produce a liquid mixture, a step of applying the liquid mixture on a substrate, a step of forming a precursor film on the substrate by drying the applied mixed liquid, a step of peeling the precursor film from the substrate and a step of firing the peeled precursor film.
