Abstract: To provide a fluorinated ether compound capable of forming a surface layer excellent in initial water/oil repellency, fingerprint stain removability, abrasion resistance and light resistance; a fluorinated ether composition and a coating liquid containing the fluorinated ether compound; an article having a surface layer excellent in initial water/oil repellency, fingerprint stain removability, abrasion resistance and light resistance and a method for producing it. A fluorinated ether compound having a poly(oxyperfluoroalkylene) chain having a unit (a) which is an oxyperfluoroalkylene unit having 5 or 6 carbon atoms, and a unit (P) which is an oxyperfluoroalkylene unit having at most 4 carbon atoms, and having at least one of a hydrolysable silyl group and a silanol group on at least one terminal of the poly(oxyperfluoroalkylene) chain via a linking group.
