In a filament winding method, while a rotating tank relatively reciprocates in a tank axial direction to a helical winding head, fibers are fed from yarn-feeding sections to the tank. After the tank turns back in the tank axial direction, a large number of fibers are wound around one domed portion and a trunk portion of the tank, and trailing ends of the large number of fibers are located at one end portion of the trunk portion. Then a piece or a small number of fibers are fed from a rotating hoop winding head to the trunk portion, and hoop winding is performed on helical winding layers formed around the trunk portion. Then, at the one end portion of the trunk portion, the large number of fibers pulled from the yarn-feeding sections of the helical winding head are cut off.
