To prevent penetrating hydrogen of the hydrogen tank and occurring buckling phenomenon, High-pressure hydrogen tank 10 possesses a liner 11 made of high-density polyethylene. A shell 12 made by winding a fiber-reinforced material for hardening is formed outside of this liner 11 to enhance liner synthesis. Hydrogen barrier layer 14 is piled up inside of the liner 11. This hydrogen barrier layer 14 prevents hydrogen filled in liner 11 from penetrating to outside.
