Abstract: A composite container is provided where FRP layers are formed by winding FRP around a metal liner so that the dome sections are reinforced while limiting an increase in the weight. The FRP layers include a hoop layer that covers the entirety of the cylindrical section in hoop winding, and dome section reinforcing layers that also cover as least the portions of the cylindrical section near the dome sections. In the dome section reinforcing layers, FRP are wound in helical form in such a manner that the orientation angle of the FRP over the cylindrical section relative to the direction of the axis of the liner continuously changes towards the center of the cylindrical section, and thus, the weight of FRP near the center of the cylindrical section is reduced.
