摘要： To provide a crosslinkable fluorinated elastomer composition which is excellent in crosslinking reactivity and of which a crosslinked product is excellent in heat resistance and chemical resistance. The crosslinkable fluorinated elastomer composition comprises a fluorinated elastomer (e.g. a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer) and an aromatic compound having at least two crosslinkable unsaturated double bonds (e.g. a compound represented by the formula (A-1)), and the crosslinked product is one obtained by crosslinking the crosslinkable fluorinated elastomer composition.
