<P>PROBLEM TO BE SOLVED: To enable joining without the problem of a cost increase by few man-hours, without risk of reducing strength of a metallic pipe and the necessity of increasing the thickness of the metallic pipe, while further securing adhesive strength in joining of the mutual metallic pipes by using an adhesive. Ž<P>SOLUTION: A joining process is used which includes a first process of applying a flux 60 to a joining object part in a surface of a first metallic pipe 40 when joining the first metallic pipe 40 to the opening end 411 to a second metallic pipe 41 having the opening end 411, a second process of filling the adhesive 50 between the joining object part after applying the inserted flux 60 and an inner wall 411a of the opening end 411 by inserting the joining object part of the first metallic pipe 40 inside the opening end 411, a third process of removing an oxide film 70 in the joining object part of the first metallic pipe 40 surface by activating the flux 60, and a fourth process of hardening the filled adhesive 50.
