Abstract
A high-pressure gas tank includes: a liner having an internal space for holding a gas; a strengthening layer stacked on the liner and having carbon fibers and a first resin; an intermediate layer stacked on at least a part of the strengthening layer; and a protective layer stacked on the intermediate layer and having glass fibers and a second resin. The intermediate layer has higher gas permeability than the strengthening layer and the protective layer.
