The present invention provides a heat-resistant hose that is excellent in low permeability of gas, fuel and the like, is nickel-free, and has excellent heat aging resistance, ozone resistance, and the like. SOLUTION: An inner layer 1 formed using acrylonitrile-butadiene rubber (NBR), a blend rubber of NBR and polyvinyl chloride (NBR-PVC), fluororubber or fluororesin, and a hydrin system formed on the outer periphery thereof. A heat-resistant hose having a laminated structure with the rubber layer 2, wherein the hydrin rubber layer 2 is formed of a rubber composition having the following (A) to (F) as essential components. (A) A hydrin rubber having an ethylene oxide content of 10 to 40 mol%. (B) Amine-based anti-aging agent. (C) A phenolic anti-aging agent. (D) Metal salt of dithiocarbamic acid (excluding nickel salt). (E) 1.8-diazabicyclo (5.4.0) undecene-7 (DBU) salt. (F) Hydrous hydrotalcite compound. [Selection] Figure 1 |
