Abstract
A welded structure constituted of a fuel filling container having an opening, and a welded part including a pipe-shaped section whose one end is disposed in the opening of the fuel filling container. A welding section is fixedly disposed around the outer periphery of the pipe-shaped section. The welding section is welded through a welding surface to the outer surface of the fuel filling container. In the welded structure, the welding section of the welded part includes a welding strength providing layer and a fuel permeation resistance layer which are coaxial with the pipe-shaped section of the welded part and radially laminated to define the annular welding surface. Additionally, at least an inner peripheral surface portion of the pipe-shaped section and an outer peripheral surface portion of the other end portion of the pipe-shaped section are formed of a fuel permeation resisting material.
