PROBLEM TO BE SOLVED: To provide a fluorine resin composition for melt molding that has excellent chemical permeation resistance. SOLUTION: The fluorine resin composition for melt molding comprises (A) a copolymer of tetrafluoroethylene and perfluoro(alkylvinyl ether), (B) a melt-flowable high molecular weight polytetrafluoroethylene directly obtained by polymerization of tetrafluoroethylene, and (C) a low molecular weight polytetrafluoroethyene obtained by the radioactive decomposition of non-melt flowable high molecular weight polytetrafluoroethylene, wherein the weight ratio of A/(B+C)=80/20 to 30/70, and (A+B)/C=99.99/0.01 to 90/10.
