Abstract
A diaphragm including a cross-linked fluororubber layer obtained by cross-linking a fluororubber composition containing a fluororubber (A) and a carbon black (B), the cross-linked fluororubber layer having a loss modulus E″ of 400 kPa or higher and 6,000 kPa or lower determined by a dynamic viscoelasticity test under conditions of measurement temperature: 160° C., tensile strain: 1%, static tension under a constant static load condition for measuring strain distribution: 157 cN, and frequency: 10 Hz.
