PROBLEM TO BE SOLVED: To obtain a fuel tank capable of improving the fuel permeability resistance of a part from a mating part overlapped with fuel tank components to a through-hole. SOLUTION: The through-hole is formed at a joining part 28 joining a flange 26 of the fuel tank, a compression part 32 compressing the flange 26 to the thickness direction is formed around the through-hole, and the distance between barrier layers 24A, 24B is short at this part. Since the thickness of resin layers 22C, 22D between the barrier layers 24A, 22B is thin, a penetration amount of the fuel is reduced, and the fuel permeability resistance is improved.
