PROBLEM TO BE SOLVED: To provide a heat-resisting air hose having excellent oil leaching resistance with minimized vibration noise. SOLUTION: In the heat-resisting air hose including an inner layer 1 and an outer layer 2 formed on the outer circumference thereof, the inner layer 1 is formed by use of an inner layer material mainly composed of silicone rubber, and the outer layer 2 is formed by use of an outer layer material mainly composed of an acrylic rubber containing 50 wt.% or more of ethyl acrylate, the acrylic rubber having a loss coefficient (tanδ) of 0.09 or more at 150°C and a storage elastic modulus E' of 7.0 MPa or more.
