PROBLEM TO BE SOLVED: To provide a fluorinated elastomer composition which gives a moldings excellent in resistance to metallic corrosion, especially generating less corrosive materials at a high temperature. SOLUTION: The fluorinated elastomer composition comprises (1) a fluorinated elastomer comprising (a) tetrafluoroethylene, (b) a perfluoro(1-5C alkyl vinyl ether) and/or a perfluoro(3-11C alkoxyalkyl vinyl ether), and (c) a cyano group containing perfluorovinyl ether, (2) a hydrotalcite compound, (3) a crosslinking agent and (4) titanium dioxide.
