A vacuum brake hose having excellent interlaminar bonding strength between a tubular inner layer and an outer layer, as well as available at low cost by mass production. The vacuum brake hose comprising the tubular inner layer formed by using acrylonitrile-butadiene rubber, a reinforcing fiber layer provided on an outer peripheral surface of the tubular inner layer and the outer layer formed on an outer peripheral surface of the reinforcing fiber layer by using chloroprene rubber, wherein the reinforcing fiber layer is impregnated with adhesive consisting essentially of components (A) to (C) and interlaminar bonding between the tubular inner layer and the outer layer is effected through the adhesive: (A) chloroprene rubber; (B) acrylonitrile-butadiene rubber; and (C) at least one filler of carbon black and a white filler.
