A brake hose has an inner rubber layer, an outer rubber layer, and at least two reinforcing layers provided between the inner rubber layer and the outer rubber layer. The reinforcing layers include an upper yarn layer, and a lower yarn layer. Polyester yarn having a tensile strength of not lower than 6.9 g per unit dtex and having a stretchability of 2.6±1.0% at 2.7 g load per unit dtex is used as lower yarn in the lower yarn layer. The braid angle of the lower yarn layer with respect to the axial direction of the hose is set at 59±2°,
