PROBLEM TO BE SOLVED: To provide a joint component for a resin fuel tank exhibiting excellent fuel permeability resistance and a welding force in a welded part with an outer peripheral part of an opening part of the resin fuel tank. SOLUTION: The joint component is composed of a body member 1 and a welding member 2 to be interposed, the body member 1 is formed of either one or two kinds or more of a low fuel permeability materials such as PA, polyester, LCP, PPS or the like, the welding member 2 is composed of a metal foil layer 21, alloy material (the alloy material where EVOH forms a matrix, and a modified HDPE forms a domain) layers 22 formed on both sides of the metal foil layer 21, and a modified HDPE layer 23 formed on the surface of each alloy material layer 22.
