Abstract: The high-pressure gas tank includes a seal member extended in a layer-like form to cover the opening recess from a surface of the liner on an outer side of the inner circumferential wall of the mouthpiece placing portion to a surface of the mouthpiece flange on a center side of the flange outer peripheral edge. In a vertical section of the high-pressure gas tank, the flange outer peripheral edge and the inner circumferential wall of the mouthpiece placing portion are formed to satisfy Dt>(Sm/Xgs)·100, where Dt denotes a width of an opening of the opening recess, said Dt being defined to be a distance between a flange outer peripheral edge-side end and an inner circumferential wall-side end of an opening of the opening recess. Sm denotes a maximum tolerance of a relative positional misalignment between the inner circumferential wall of the mouthpiece placing portion and an outer circumferential end of the flange outer peripheral edge, and Xgs [%] denotes a breaking elongation of the seal member.
