PROBLEM TO BE SOLVED: To inexpensively and easily manufacture a reinforced pipe with high compression strength which can be applied to various materials. SOLUTION: The reinforced pipe 10 is formed by spirally winding an outer linear member 13 and an inner linear member 14 in the opposite direction each other to the outside face and the inside face of a pipe 12 made of a plastic material. The reinforced pipe 10, which is strong against deformation and crush caused by compression force, can be inexpensively and easily manufactured by crossing the spiral in such a manner.
