Therefore, the repair member is pressed against the outer peripheral surface of the synthetic resin pipe to electrically Defects such as pinholes and dents can be easily repaired simply by energizing the hot wire. Further, since the heating wire is deeper in the buried position as it approaches the center from the outer peripheral edge of the plate, heat is generated when the defect is set in the center of the plate and fusion bonding is performed. The heating wire is not exposed on the concave curved surface. Therefore, there is no risk of causing a fire accident by igniting the gas or the like in the synthetic resin pipe from the heating wire that has generated heat.
