[Solution] A seal member comprises a composite material that includes a fluorine-based elastomer and a fluororesin. The fluororesin includes at least one of polytetrafluoroethylene (PTFE), tetrafluoroethylene perfluoro alkyl vinyl ether copolymer (PFA), tetrafluoroethylene hexafluoropropylene copolymer (FEP), and tetrafluoroethylene ethylene copolymer (ETFE). The seal member has a compression set at 150°C of 90% or less. |
