Abstract
A high-pressure tank that enables end portions of a first reinforcing layer wound around a body of a liner to sufficiently contribute to the strength of dome portions of the tank. In the high-pressure tank, a reinforcing layer includes the first reinforcing layer that covers the body and a second reinforcing layer that covers the first reinforcing layer and side end portions of the liner. The first reinforcing layer includes a hoop reinforcing layer formed through hoop winding of a resin-containing fiber bundle in a midsection of the body, and a helical reinforcing layer arranged in parallel with the hoop reinforcing layer along the axis direction of the high-pressure tank and formed through helical winding of the fiber bundle in a section on at least one end side of the midsection, the helical reinforcing layer forming a part of the dome portions.
