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 finger print 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 (±²) having a structure of block (±)-block (²) or a structure of block (²)-block (±)-block (²), formed by linking a block (±) comprising at least three C 1-3 oxyperfluoroalkylene units of at least one type and a block (²) having C 4-15 oxyperfluoroalkylene units of at least one type, wherein the proportion of the C 4-15 oxyperfluoroalkylene units is at least 30 mol% among all oxyperfluoroalkylene units constituting the block (²), and which has a hydrolysable silyl group on at least one terminal of the poly(oxyperfluoroalkylene) chain (±²) via a linking group.
