A repair pipe is placed between the cut ends e and f of the resin pipe a, and the repair pipe is fused to the other end f of the resin pipe a using another joint member C. Then, the end e of the resin pipe a and the repair pipe were fused together using the joint member C that had been inserted in advance. In addition, the joint member c used at this time,
As shown in Fig. 6, c is a cylindrical joint body g with a coil h embedded therein which generates heat when energized, and is inserted into a joint member C. resin pipe a
The heat generated by the coil h melts the resin in the area where the repair pipe and the repair pipe come in contact with each other, thereby performing fusion bonding.

, f, but if this gap is larger than necessary, a portion of the coil h embedded in the joint member C will not come into contact with the resin pipe a. Therefore, if a sufficient welding area is not obtained and electricity is applied in this state, abnormal heat generation will occur from the portion of the coil h that is not in contact with the resin tube a, the resin will deteriorate, and welding performance will not be obtained. This may cause such inconvenience. Furthermore, since two joint members c and c are required for repairing the pipe, there are inconveniences such as time-consuming repair work and increased work costs and member manufacturing costs.

Further, the fused portions 21 and 22 are formed to have an inner diameter large enough to allow the resin pipe 1 to be inserted therein. However, since the repair pipe 2 and the resin pipe 1 are fused together, the gap between them must not be too large. Further, the coil 3 is embedded so as to surround the entire fused portion 21, 22, so that a sufficient bonding area by fusion can be secured.
