PROBLEM TO BE SOLVED: To provide a pipe connecting structure, a pipe connecting structure set and a pipe connecting method using the same, capable of reducing a gap on a connecting part, and providing an integrated connecting structure free from the leakage, by electric welding, when pipes made out of thermoplastic resin are connected. SOLUTION: This pipe connecting structure comprises a thermoplastic resin pipe main body having a socket and a spigot on its both ends, or a thermoplastic resin joint main body having sockets for inserting the spigots of the thermoplastic resin connecting pipe and a thermoplastic resin connected pipe on its both ends, and an electrically welded cylindrical part mounted along an inner peripheral face near the socket of the pipe main body or the joint main body. The electrically welded cylindrical part is composed of a thermoplastic resin cylindrical body, and a heating wire attached to the cylindrical body and generating the heat by energization to melt the cylindrical body.
