Multilayered Tubular Shaped Object

Abstract: [Problem] To provide a multilayered tubular shaped object having high flexibility and less apt to have wrinkles in the inner surface. [Solution] A multilayered tubular shaped object 1 comprises an inner layer 2, an outer layer 3, and an interlayer 4 interposed between the inner layer 2 and the outer layer 3 to bond these layers to each other. The inner layer 2 comprises a polyolefin as a main component, the outer layer 3 comprises a thermoplastic polyurethane as a main component, and the interlayer 4 comprises an adhesive polyolefin as a main component. The proportion of the sum of the thickness T3 of the outer layer 3 and the thickness T4 of the interlayer 4 to the wall thickness TT of the multilayered tubular shaped object 1 is 0.7-0.92.
