Claim:
A gas tank for a high-pressure gas, comprising: a container main-body into which the high-pressure gas is filled; a first heat insulation section provided on an outer surface of the container main-body; a fixing-member fitting region provided at a portion of the outer surface of the container main-body; a fixing member, wherein a fitting surface being a part of surfaces of the fixing member is in contact with the fixing-member fitting region, the fixing member is fixed to an external structure so that the container main-body is fixed to the external structure, and the first heat insulation section is sandwiched between the fixing member and the container main-body; and a second heat insulation section that is provided on a surface of the fixing member other than the fitting surface and covers only the surface of the fixing member, wherein the second heat insulation section is a layer comprising a thermal-foam heat-insulation coating material, and the second heat insulation section foams by an increase in temperature to become a heat insulation layer.
