To provide a lining method for a pipeline capable of improving the working efficiency in lining construction, and reinforcing a lining layer.

This lining method for the pipeline includes a first process for abutting and placing a spiral tube 4 made of a thermally-meltable lining material 3 including a heating wire 2, on an inner face of the pipeline 1, and a second process for melting and integrating the lining material 3 of the spiral tube 4 by heat generated when the predetermined voltage is applied to the heating wire 2 of the lining material 3, and forming the lining layer 5 fused to the inner face of the pipeline 1.
