PURPOSE:To produce the title molding excellent in mechanical strengths and flexibility, by molding a mixture of two specified copolymers both of which contain fluorine and crosslinking the obtained molding by irradiation with an ionizing radiation. CONSTITUTION:A mixture of a copolymer of tetrafluoroethylene with a 2-4C alpha-olefin (e.g., tetrafluoroethylene/propylene copolymer) with a copolymer of crystallinity >=5%, prepared by copolymerizing vinylidene fluoride with a fluoromonomer (e.g., vinylidene fluoride/fluoroethylene copolymer), is molded into a predetermined shape, and the obtained molding is crosslinked by irradiation with an ionizing radiation. A decrease in the mechanical strengths and heat resistance due to irradiation with an ionizing radiation can be prevented, so that a crosslinked molding of a fluorine-containing elastomer excellent in mechanical strengths and flexibility can be obtained.
