    摘要: The present invention provides a member to be compressed for an electrochemical device, containing at least one copolymer selected from the group consisting of (1) a copolymer containing a tetrafluoroethylene unit and a fluoroalkyl vinyl ether unit, the copolymer having a content of the fluoroalkyl vinyl ether unit based on all the monomer units of the copolymer of 4.3% by mass or more and less than 5.5% by mass, and having a melt flow rate of 10 to 23 g/10 min, and (2) a copolymer containing a tetrafluoroethylene unit and a fluoroalkyl vinyl ether unit, the copolymer having a content of the fluoroalkyl vinyl ether unit based on all the monomer units of the copolymer of 5.5% by mass or more and 8.0% by mass or less, and having a melt flow rate of 23 to 68 g/10 min.
