To provide a fluorinated ether compound, a fluorinated ether composition and a coating liquid, whereby it is possible to form a surface-treated layer which has high initial water/oil repellency and which is excellent in abrasion resistance and fingerprint stain removability, and a substrate having a surface-treated layer and a method for its production. A fluorinated ether compound which has a poly(oxyperfluoroalkylene) chain ((αβ)n) made of at least two units (αβ) linked to one another, and which has a hydrolysable silyl group on at least one terminal of the chain ((αβ)n) via a linking group, wherein each unit (αβ) is a poly(oxyperfluoroalkylene) group comprising one to three groups (α) made of at least one type of a C1-2 oxyperfluoroalkylene group and one to three groups (β) made of at least one type of a C3-6 oxyperfluoroalkylene group.
