Abstract: A member to be compressed for an electrochemical device obtained by crosslinking a crosslinkable composition containing a fluorine-containing elastomer containing a unit based on at least one crosslinkable group-containing monomer selected from the group consisting of a crosslinkable group-containing monomer (1) represented by the general formula (1): CX12═CF—Rf1—X2 wherein each X1 independently represents H or F, and Rf1 represents a fluorinated alkylene group or a fluorinated oxyalkylene group, and X2 represents I or Br; and a crosslinkable group-containing monomer (2) represented by the general formula (2): CX32═CX3—Z1—CX3═CX32 wherein each X3 independently represents H, F, an alkyl group or a fluorinated alkyl group, and Z1 represents an alkylene group, a fluorinated alkylene group, a cycloalkylene group, a fluorinated cycloalkylene group, an oxyalkylene group or a fluorinated oxyalkylene group.

Abstract: Provided is a member to be compressed for an electrochemical device obtained by crosslinking a crosslinkable composition containing a fluorine-containing elastomer, wherein the fluorine-containing elastomer exhibits a difference δG′ (G′(100° C.)−G′(180° C.)) between the storage elastic modulus G′(100° C.) at a measurement temperature of 100° C. and the storage elastic modulus G′(180° C.) at a measurement temperature of 180° C., in the dynamic viscoelasticity test (strain amplitude: 0.5 Deg; frequency: 100 CPM) with a rubber process analyzer satisfying the following conditions: 40 kPa
