PROBLEM TO BE SOLVED: To perform proper fusion regardless of a power supply capacity in an execution field by arranging a plurality of bar codes for outputting substantially same fusion energy with differential information. SOLUTION: By an electro-fusion joint 10, a resin pipe 12 and a resin pipe 14 made of a thermoplastic resin such as polyethylene and polybutene are connected to each other. The electrofusion joint 10 is provided with a cylindrical joint main body 16 made of the same thermoplastic resin as the resin pipes 12, 14. Receiving ports for receiving the resin pipes 12, 14 are formed on both end parts of the joint main body 16, and a coil shaped heating body is disposed in the vicinity of an inner surface. The both end pats of the heating body are connected to joint terminals 18a, 18b protruded and formed to an outer peripheral surface of the joint main body 16. A bar code display part 20 is formed on an outer peripheral surface of the joint main body 16. The bar code display part 20 is provided with bar codes 20a, 20b.
