A hydrin rubber composition free from nickel and excellent in heat aging resistance, ozone resistance, storage stability, and the like is provided which essentially contains the following components: (A) a hydrin rubber containing 10 to 40 mol % of ethylene oxide; (B) an amine-based antioxidant; (C) a phenol-based antioxidant; (D) a metal dithiocarbamate excluding nickel salts; and (E) a hydrotalcite compound. Also provided is a heat-resistant hose having a layered structure including an inner layer and a hydrin-based rubber layer disposed on the outer surface of the inner layer. The hydrin-based rubber layer is composed of a rubber composition containing (F) a 1,8-diazabicyclo[5.4.0]undecene-7 salt, in addition to the foregoing (A) to (E).
