Abstract
A high-pressure tank includes a container main body () constituted of a body () and dome portions () disposed on both ends of the body, and a reinforcing layer () formed such that a fiber member is wound around an outer periphery of the container main body. The reinforcing layer includes a hoop winding layer () formed by hoop winding that winds the fiber member such that a winding angle is approximately perpendicular to a central axis of the body, and a high helical winding layer () formed by high helical winding that winds the fiber member such that a winding angle is inclined with respect to the central axis compared with the hoop winding, and the high helical winding layer extends to the dome portion. The high helical winding layer includes a thick portion having a thickness at an outer side part of a boundary position between the body and the dome portion, which thickness is thicker than a thickness at a part positioned on the body. The hoop winding layer is formed from the body to the dome portion where the thick portion is formed, as a layer at an outer diameter side of the high helical winding layer.
