Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electric fusing joint excellent in adhesion between multilayer molding resin layers and excellent in reliability. SOLUTION: This electric fusing joint comprises an inner cylinder member layer burying a heating wire in an internal peripheral part and an outer cylinder member layer provided by molding thermoplastic resin in an outer surface of this inner cylinder member layer. Here, the outer cylinder member layer is formed by two layers or more multilayer resin layer, between the multilayer resin layers of this outer cylinder member layer, a boundary layer (layer of contrast different from core layer by polarizing microscope) of thickness exceeding 0.5mm is formed, so as to increase elongation, adhesion and a mechanical characteristic are improved.
