A fluororubber composition contains 0.1 to 50 parts by weight of an epoxidized polybutadiene with respect to 100 parts by weight of a fluororubber. As the fluororubber, a vinylidene fluoride-hexafluoropropylene copolymer (FKM), a tetrafluoroethylene-propylene-based copolymer (FEPM), a tetrafluoroethylene-perfluoroalkyl vinyl ether-based copolymer (FFKM), or the like is exemplified. The fluororubber composition may further contain a vulcanizing agent or the like.
