Abstract: A method for producing an article including a substrate and a surface-treating layer formed from a surface-treating agent containing a fluorine-containing silane compound formed thereon, the method including: simultaneously depositing Si and another metal on the substrate to form an intermediate layer containing a composite oxide containing Si; and forming a surface-treating layer directly on the intermediate layer, wherein, the fluorine-containing silane compound is at least one fluoropolyether group-containing compound represented by the following formula (1) or (2): RF1α—XA—RSiβ  (1) RSiγ—XA—RF2—XA—RSiγ  (2) where RF1, RF2, RSi, XA, α, β and γ are as defined herein.

Abstract: A fluoro(poly)ether group-containing silane compound represented by any of the formulae (A1), (A2), (B1), (B2), (C1), or (C2). In the formulae, PFPE is each independently at each occurrence a group represented by the formula: —(OC3F6)d—, wherein the repeating unit OC3F6 of the formula includes a branched structure, and d is an integer of 2 or more and 200 or less. The symbols are as defined in the description.
