PROBLEM TO BE SOLVED: To provide a laminated resin tube making compatible both high pressure resistance and bending flexibility, and provided further with high flame retardancy. SOLUTION: In this laminated resin tube comprising two layers of at least an inner layer tube and an outer layer tube, the inner layer tube is constituted of a resin excellent in the bending flexibility, for example, a polyurethane resin, and the outer layer tube is constituted of a resin having performance of high breaking stress, for example, a polyamide resin. A thickness of the inner layer tube is 1.0-3.0 mm, and a thickness of the outer layer tube is 0.01-1.5 mm. A halogen-free flame retardant may be added also to a resin material.
