PROBLEM TO BE SOLVED: To provide a tank structure to suppress and prevent the occurrence of malfunction being micro leakage through a second stage part mounted part due to arrangement of a barrier layer in a fuel tank made of conventional type resin. SOLUTION: A tank element 10 consists of a first resin layer 11 on the inside; a barrier layer 12; and a second resin layer 13 on the outside, and a second stage part 14 is adhered to the tank element 10 for integral formation. The tank element 10 consists of a plurality of resin layers and its outermost layer 13 is formed of gas barrier properties resin, and the second stage part 14 is formed of the same as the gas barrier properties resin or gas barrier properties having excellent adhesion to the gas barrier properties resin. This constitution improves sealing properties since gas barrier properties resins are adhered together when the second stage part is adhered to the tank element, and eliminates worry about leakage of gas to the outside.
