Abstract
The present invention aims to provide a modified fluorine-containing copolymer excellent in crack resistance, a fluororesin molded article, and a method of producing a fluororesin molded article. The present invention includes a modified fluorine-containing copolymer consisting only of tetrafluoroethylene units and perfluoro(alkyl vinyl ether) units. The copolymer is modified by irradiation with radiation at an irradiation temperature not higher than the melting point of the copolymer but not lower than 200° C.
