Abstract
A high-pressure vessel includes a liner, an outer layer, a ferrule, and a seal member. The liner has a cylindrical shape, and is made of a first resin. The outer layer is joined to an outer peripheral surface of the liner, and is made of a second resin having a linear expansion coefficient that is lower than a linear expansion coefficient of the first resin. The ferrule is made of metal, is at least partly disposed radially inward of an inner peripheral surface of the liner, and is configured to provide communication between an internal space of the high-pressure vessel and an outside of the high-pressure vessel. The seal member is disposed between the inner peripheral surface of the liner and the ferrule, and is configured to seal a gap between the inner peripheral surface of the liner and the ferrule.
