PROBLEM TO BE SOLVED: To provide an electric fused saddle joint and a method of manufacture of this electric fused saddle joint wherein moving of a heating wire is prevented from being generated at injection molding time, heat transfer efficiency to a connected pipe is improved, a fusing time carrying a current can be shortened. SOLUTION: In an electric fused saddle joint 1 forming a helical groove in one surface, integrally molding a thermoplastic resin-made inner member 7 having a bare heating wire 8 received in this helical groove and an outer member forming a saddle joint main unit, a lock resin part is formed in one surface side of the inner member 7, the bare heating wire 8 is fixed to the inner member 7, this one surface side is arranged in an inner surface side of a saddle main unit 2, the heating wire 8 is exposed. Here, the lock resin part may be a film-shaped resin thin film pressed and thermally fused by a press disk from above the helical groove, or molded by an amorphous resin band molded my heat fusing the upward of the helical groove alternately discontinuously by an electric iron or the like. |
