PURPOSE:To obtain a plastic molded item by joining a plastic tube to another plastic tube via a high frequency generator. CONSTITUTION:A resin tube 10 is composed by providing a heating layer 2 formed by a bulk material composed of a kneaded material of thermoplastic synthetic resin or a different natured material having an affinity thereto and an induction heating thermal element to a surface of a tube body 1 of the thermoplastic synthetic resin or crosslinked polyethylene material, and if necessary by providing a protective layer 3 of the thermoplastic synthetic resin or non-crosslinked polyethylene to the surface of the heating layer. Since the heating layer 2 is formed directly or via the protective layer 3 on the surface of the tube body 1 thereby, a joining part can be directly welded via a high frequency generator. |
