PROBLEM TO BE SOLVED: To provide a radiation-crosslinked fluorine-containing copolymer enabling the radiation crosslinking under a mild condition, and having more improved mechanical characteristics and compression set characteristics. SOLUTION: The radiation-crosslinked fluorine-containing copolymer is obtained by irradiating a fluorine-containing copolymer composition obtained by compounding 1-20 pts.wt. triallyl isocyanurate polymer having 500-100,000 number average molecular weight Mn with 100 pts.wt. tetrafluoroethylene-perfluoro(alkyl vinyl ether) copolymer having≤10 J/g heat quantityΔH for melting a crystal with radiation.
