The invention prevents rupture of the outer layer resulting from the coil digging into same, which is associated with partial hose collapse and deformation. By knitting the reinforcing threads or reinforcing fibers of a second reinforcing layer (4) into a tubular shape and integrally laminating along the outside of a coil (3) and integrally laminating an outer layer (5) along the outside of the second reinforcing layer (4), the second reinforcing layer (4) is disposed between the coil (3) and the outer layer (5) so as to cover the outer surface of the coil (3). Therefore, even if a part of the coil (3) in the axial direction collapses locally into a flat shape in the radial direction and is compressed and deformed into a substantially elliptical cross-sectional shape as a result of the local collapsing and deformation of a part of a hose (A) in the radial direction, the areas thereof that are bent substantially into V-shapes and are pointed do not directly impinge on and dig into the inner surface (5a) of the outer layer (5). |
