PROBLEM TO BE SOLVED: To provide a fluorine-containing copolymer excellent in heat resistance, chemical resistance, weatherability and stress crack resistance as well as excellent in adhesiveness, and to provide a laminate of the copolymer and a coated article. SOLUTION: The fluorine-containing copolymer contains a repeating unit (a) based on tetrafluoroethylene, a repeating unit (b) based on CF<SB>2</SB>=CFOCF<SB>2</SB>CF<SB>2</SB>CF<SB>3</SB>, a repeating unit (c) based on CF<SB>2</SB>=CFOCF<SB>3</SB>and/or CF<SB>2</SB>=CFOCF<SB>2</SB>CF<SB>3</SB>, and a repeating unit (d) based on a polymerizable hydrocarbon monomer having a dicarboxylic acid anhydride group. Based on the total molar amount of the repeating unit (a), repeating unit (b), repeating unit (c) and repeating unit (d), the copolymer contains the repeating unit (a) by from 75 to 99.79 mol%, the repeating unit (b) by from 0.1 to 10.0 mol%, the repeating unit (c) by from 0.1 to 10.0 mol%, and the repeating unit (d) by from 0.01 to 5.0 mol%, and has a volume flow rate of 0.1 to 1,000 mm<SP>3</SP>/sec.
