Provide a hose with excellent mechanical properties at high temperatures. It has a crosslinked fluororubber layer obtained by crosslinking a fluororubber composition containing fluororubber (A) and carbon black (B), and the crosslinked fluororubber layer is subjected to a dynamic viscoelasticity test (measurement temperature: 160 ° C., tensile Strain: 1%, initial load: 157 cN, frequency: 10 Hz) and a loss elastic modulus E ″ is 400 kPa or more and 6000 kPa. |
