Fluorine-containing crosslinkable elastomer composition and crosslinked product thereof

Provided is a fluorine-containing crosslinkable elastomer composition of exceptional crosslinking reactivity, the crosslinked product of which has exceptional heat resistance and chemical resistance. This fluorine-containing crosslinkable elastomer composition contains a fluorine-containing elastomer (e.g., a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer), and an aromatic compound having two or more crosslinkable unsaturated double bonds (e.g., a compound represented by the formula (A=1)), the crosslinked product being obtained through crosslinking of the fluorine-containing crosslinkable elastomer composition.
