Of the tip of the nozzle 15, the distance from the tip 15a in the moving direction of the belt 11a to the belt 11a is made smaller than that of the tip 15b on the opposite side. Then the molten metal 13 ejected through a nozzle port 14 onto the surface of the belt 11a is filled in the spacing between the nozzle 15 surface and the belt 11a surface and is cooled by the belt 11a; at the same time, the molten metal is made into a light-gage strip and is carried away. The flow in this stage is contracted in the moving direction of the molten metal, by which the molten metal is made more easily into laminar flow. An ultraquickly cooled light-gage strip 16 having a good surface characteristic is thus obtd.
