Abstract
A method for manufacturing a high-pressure tank includes an arrangement step of arranging, in a cavity of a mold, an intermediate including a liner and a fiber bundle wound around the liner, and an impregnation step of impregnating the fiber bundle with a molten resin in the cavity by increasing a pressure on the molten resin injected into the cavity. The impregnation step includes a pressure increasing step of increasing an internal pressure of the intermediate when increasing the pressure on the molten resin.
