<P>PROBLEM TO BE SOLVED: To provide a fluorine-containing elastomer composition which provides a sealing material whose ozone resistance is improved and which has good heat resistance. Ž<P>SOLUTION: This fluorine-containing elastomer composition comprises a perfluoroelastomer (A) comprising (a) 20 to 37% by mole of a perfluoroalkyl vinyl ether unit, (b) 0.1 to 2.5% by mole of a monomer unit having at least one, as a cross-linking part, selected from the group consisting of a nitrile group, a carboxy group and an alkoxycarbonyl group and (c) 61.5 to 79.9% by mole of a tetrafluoroethylene unit, and a specific cross-linking agent (B).
