Abstract
A method for manufacturing a high-pressure tank including a liner and a reinforcing layer covering an outer surface of the liner includes: forming a cylinder member made of a fiber-reinforced resin; forming a pair of dome members made of the fiber-reinforced resin; and forming a reinforcing body that is the reinforcing layer by joining the cylinder member and the dome members. When forming the cylinder member, a resin-impregnated fiber sheet is wound around an outer peripheral surface of a mandrel to form a cylinder body, and a resin-impregnated fiber bundle is then wound so as to overlap the cylinder body.
