Fluorine-containing ether compounds, fluorine-containing ether compositions and coating liquids capable of forming a surface layer excellent in initial water and oil repellency, fingerprint stain removal, abrasion resistance, light resistance and chemical resistance, articles having a surface layer and the like Providing manufacturing methods. Fluorine-containing ether compound represented by A-O- (R f1 O) m- Q 1 (R 1 ) b . However, A is a perfluoroalkyl group having 1 to 20 carbon atoms, R f1 is a perfluoroalkylene group, m is an integer of 2 to 500, and (R f1 O) m is two or more kinds having different carbon atoms. It may consist of R f1 O, Q 1 is a (b + 1) -valent perfluorohydrocarbon group which may have a hydroxyl group, and R 1 has at least one hydrolyzable silyl group 1 It is an organic group of valence, b is an integer of 2 or more, and b R 1s may be the same or different. |
