PROBLEM TO BE SOLVED: To provide an oil feed pipe easily realizing particularly necessary and sufficient hermeticity while manufacturing a mouthpiece and a conduit pipe as different members according to requirements in recent years. SOLUTION: In the fuel feed pipe 1 where a joint 12 of the cap 2 is joined to an end 16 of the conduit pipe 3 and these cap 2 and conduit pipe 3 are integrated, there is such a relation that a joint outer surface 17 of the cap 2 is fitted into an end inner surface 18 in the contact surface condition. The cap 2 and the conduit pipe 3 are integrated by performing seam welding in an area S where the joint outer surface 17 and the end inner surface 18 fitted in the contact surface condition are overlapped.
