PROBLEM TO BE SOLVED: To provide a fluorine-containing elastomer composition which does not generate an environmentally harmful substance, has extrusion processability, heat resistance, and oil resistance with good balance, and gives a high-strength elastomer. SOLUTION: The fluorine-containing elastomer composition includes 100 pts.wt. of a fluorine-containing elastomer mixture obtained by mixing a tetrafluoroethyleneα-olefin copolymer with an ethylene-ethylenic unsaturated ester copolymer and 0.5-10 pts.wt. of an organic peroxide which is based on a dialkyl peroxide. In the fluorine-containing elastomer composition, the ratio of the tetrafluoroethyleneα-olefin copolymer to the ethylene-ethylenic unsaturated ester copolymer is in the range of from 95:5 to 80:20.
