PROBLEM TO BE SOLVED: To quickly join fitting parts of a pipe mutually without any clearance. SOLUTION: A first pipe 11 and a second pipe 12 are made of resin respectively and a fitting part 22 is formed by fitting their respective ends together. A conductive heating member 21 is arranged in the fitting part 22, a coil part 32 of a heating device 31 is approached to the fitting part 22 formed by fitting, and a high frequency current is fed to the coil in the coil part 32. The conductive heating member 21 is thus heated by electromagnetic induction heating, the fitting part 22 is softened by the heat, and the both pipes are joined with each other under the solid phase. |
