Abstract
Abstract To provide a composition for forming an antifouling film with which an antifouling film excellent in stain resistance, scratch resistance, solvent resistance, etc. can be formed and an optical component having such an antifouling film, for example, an anti-reflection filter. An antifouling film is formed by a composition for forming the antifouling film containing an alkoxysilane compound having a perfluoropolyether group indicated by the following general formula (1): R f (COR 1 -R 2 -Si(OR 3 ) 3 } j (1) where, in the formula, R f indicates a perfluoropolyether group, R 1 indicates a bivalent atom or group, R 2 indicates an alkylene group, R 3 indicates an alkyl group, and j is 1 or 2.
