The high pressure tank has a cylindrical liner and a fiber reinforced plastic covering the outer circumferential surface of the liner. At least one end of the liner is splittable. The liner includes a cylindrical body and a lid. The O-ring is interposed in the joining surface between the liner body and the lid body in the circumferential direction. The joining surface has a seal surface in contact with the O-ring. One of the liner body and the lid has a deformable portion that is deformed toward the seal face. This configuration makes it possible to reliably seal the divided portion of the liner when the inside of the high pressure tank is under high pressure. |
