Zusammenfassung:	Provided is a nozzle for descaling a steel plate, capable of efficient descaling. A descaling nozzle (1) is configured in such a manner that a discharge section (20) at the tip of the nozzle has a discharge hole (main flow orifice)(15) and branch holes(flow diverting orifices)(19), and the discharge hole (15) and the branch holes(19) are provided so as to communicate with a large-diameter section (18) forming a tube-shaped flow path. The branch holes (19) discharge a portion of the flow of water within the large-diameter section so as to generate cavitation at the boundary between the portion of the flow of water and the flow of water discharged from the discharge hole (15).
