PROBLEM TO BE SOLVED: To provide a multi-layer pressure-resistant tube which is harder to burst than a conventional one. SOLUTION: A reinforcement thread 3 is sandwiched between an inner layer side resin layer 1 and an outer layer side resin layer 2, and a monofilament is used as the reinforcement thread 3. Portions that the inner layer side resin layer 1 and the outer layer side resin layer 2 come in contact with are mutually fastened. Since the reinforcement thread is sandwiched between the inner side resin layer and the outer layer side resin layer, and the monofilament is used as the reinforcement thread, a fluid cannot soak through the reinforcement thread made of the mutual monofilament of an inner layer and an outer layer into the tube from the end surface of the tube in a connected tube joint.
