To provide a resin composite hose having excellent permeation resistance to a transported fluid, while excellent preventing flapping deformation by a resin layer.

This resin composite hose 10 is formed as a multilayered structure of the resin layer 12 in the middle of a cross section as a barrier layer having permeation resistance to the transported fluid, an inner rubber layer 16 as an inner surface layer inside of the resin layer 12 and an outer rubber layer 14 outside of the resin layer 12. The whole shape is formed in the shape of having curved portions 10-1, 10-2 and 10-3 in a part in at least the hose axial direction, forming a large diameter on one end in the hose axial direction to the other end, and further continuously increasing a diameter in the curved portions 10-1, 10-2 and 10-3 over to one end side terminal of a large diameter from a curve beginning end on the other end side of a small diameter.
