<p>PROBLEM TO BE SOLVED: To provide an electro-fusion joint which can certainly and strongly joint even crosslinking thermoplastic resin excellent in durability and chemical resistance, and in which leakage may not be caused in a joint part. SOLUTION: In this electro-fusion joint 1 having an outer shell formed of crosslinking thermoplastic resin and a short cylindrical appearance, a heating element 2 is buried in a resin layer 3 in the part of the inner circumference of the short cylinder where a crosslinking thermoplastic resin pipe is jointed, and the resin layer 3 that the heating element 2 is buried is formed of a resin composition including a modified polyolefine copolymer resin having adhesive property.</p> |
