PROBLEM TO BE SOLVED: To provide a modified fluorine-containing copolymer and a fluororesin molded article which are excellent in crack resistance and heat resistance.SOLUTION: The modified fluorine-containing copolymer is obtained by irradiating a copolymer with radiation at a temperature equal to or lower than the melting point of the copolymer. The copolymer is at least one copolymer selected from the group consisting of a copolymer comprising a tetrafluoroethylene unit and a perfluoro(alkyl vinyl ether) unit, and a copolymer comprising a tetrafluoroethylene unit and a hexafluoropropylene unit and has 10-10,000 functional groups per 10carbon atoms in total. |
