PURPOSE:To quicken production speed and to reduce production cost by injecting molten metal into cooling liquid layer from plural nozzles and swinging a molten metal vessel at the verosity fixed by the specific equation. CONSTITUTION:A rotating drum 1 for forming cooling liquid layer 2 in an inner wall by centrifugal force is prepared. The molten metal 5 is injected into the liquid layer 2 from the molten metal vessel 3 having plural nozzles 1 as plural jet flows. The jet flows are immersed into the liquid layer 2 and changed into the jetting state, film boiling state (a), over cooling liquid state (b) and fine wire of solid state (c). Then, as the molten metal vessel 3 is rotated at the fixed verosity Vr showing in the equation I, strand wire having desirable pitch P is formed by the fine wires 11. By this method, the production speed of the strand wire is quickened and the production cost is reduced.
