PROBLEM TO BE SOLVED: To reconcile improvement of fatigue resistance and reduction of a volume expansion amount. SOLUTION: A brake hose comprises an inner pipe layer 12 formed of a rubber material, a lower yarn layer 14 formed by braiding bobbin threads 15, an intermediate rubber layer 16, a upper yarn layer 18 formed by braiding needle threads 19, and a skin rubber layer 20. The lower yarn layer 14 is formed of the bobbin threads 15 having a first adhesion film adhered to the inner pipe layer 12 and the intermediate rubber layer 16. The upper yarn layer 18 is formed of the needle thread 19 having a second adhesion film adhered to the intermediate rubber layer 16 and the skin rubber layer 20.
