PROBLEM TO BE SOLVED: To make it possible to impact sufficient peeling strength and good flexibility as well to a shell. SOLUTION: An insert tube 40 consisting of a member to be fused with a shell member 30 is inserted and arranged to the inner side of a helical pipe 10 and the shell member 30 in a molten state is projected inward through pitch direction spacings 11 of the helical pipe 10 from the interspersed stitch 21 portions of the dotted net-liche pipe 20. The projecting parts 31 thereof are fused to the insert tube 40.
