PROBLEM TO BE SOLVED: To provide a corrugated hose for transporting fluid, capable of inexpensively manufacturing the whole hose with excellent workability, by excellently molding a corrugated portion even in a resin composite hose having a resin layer in the middle of a cross section. SOLUTION: This corrugated hose 10 for transporting the fluid is constituted by laminating an inner rubber layer 16 and an outer rubber layer 14 on a resin layer 12 as a barrier layer. The corrugated portion is arranged in at least a part in the hose axis direction. Its corrugate portion 22 has an inner diameter of the valleys 22B smaller than an inner diameter of a straight-shaped portion 20 in the hose 10, and has an outer diameter of the hills 22A equal to or smaller than an outer diameter of the straight-shaped portion 20.
