PROBLEM TO BE SOLVED: To obtain a perfluoropolyether-modified silane which has water/oil repellency, parting properties, chemical resistance, lubricity, durability, antifouling properties and fingerprint wipe-off property due to absence of a polar group, is useful as a surface treating agent for coating the surfaces of various kinds of substrates, is applicable to an antireflection filter that has been formed with a cured coating film on the surface, is hardly stained, has the stain to be readily wiped off, is excellent in slipperiness on the surface, is hardly damaged and keeps these performances for a long period of time. SOLUTION: The perfluoropolyether-modified silane is represented by formula (1) (Rf is a bifunctional straight-chain perfluoropolyether group; R is a 1-4C alkyl group or phenyl group; X is a hydrolyzable group; (n) is 0-2; (m) is an integer of 1-5; (a) is 2 or 3).
