PROBLEM TO BE SOLVED: To provide a heat-resistant hose with superior heat resistance for use in an air hose for an automobile. SOLUTION: This heat-resistant hose is formed by stacking a chloroprene rubber layer 2 on the outer circumference of an annular acrylonitrile-butadiene copolymer rubber layer 1. The chloroprene rubber layer 2 is formed of chloroprene rubber composition using the following A as an essential component and the acrylonitrile-butadiene copolymer rubber layer 1 is formed of acrylonitrile-butadiene copolymer rubber composition using the following A as the essential component. A: At least, one of amine-ketone based antioxidant or longer chain alkyl-substituted diphenylamine-based antioxidant. COPYRIGHT: (C)2004,JPO
