Abstract
A high-pressure tank configured to store a fluid includes: a liner; and a fiber-reinforced resin layer configured to cover surface of the liner. The liner includes: a cylindrical liner portion in a cylindrical shape; and dome liner portions in a dome shape, each dome liner portion being connected with the cylindrical liner portion, such that an outer surface of the dome liner portion is inclined at a predetermined angle to an outer surface of the cylindrical liner portion. The fiber-reinforced resin layer includes a hoop layer provided by hoop winding that winds the fiber substantially perpendicularly to a central axis of the cylindrical liner portion. The hoop layer is formed, such that an outer surface of the hoop layer has a smaller angle than the predetermined angle to the outer surface of the dome liner portion at a boundary between the hoop layer and the dome liner portion.
