PROBLEM TO BE SOLVED: To provide a fluorine-containing elastomer composition which is excellent in metal corrosion resistance, particularly is less in generation of corrosive materials at a high temperature. SOLUTION: A fluorine-containing elastomer is characteristically composed of (1) a fluorine-containing elastomer consisting of a tetrafluoroethylene, a perfluoro (1-5C alkyl vinyl ether) or perfluoro (3-11C alkoxy alkyl vinyl ether), and a cyano group-containing perfluoro vinyl ether, (2) a hydrotalcite compound, (3) a crosslinking agent, and (4) a carbon black.
