Abstract
A method for producing a high-pressure tank capable of winding a reinforcing fiber bundle around a liner without deteriorating tank performance. The method for producing a high-pressure tank by winding a resin-impregnated strip-shaped reinforcing fiber bundle around a rotating liner so as to form a fiber-reinforced resin layer on the outer surface of the liner includes while winding the strip-shaped reinforcing fiber bundle around the liner, concurrently winding another bundle of fibers narrower than the strip-shaped reinforcing fiber bundle around the liner so as to cross the strip-shaped reinforcing fiber bundle.
