PURPOSE: A nozzle apparatus for uniformly spraying molten steel is provided to uniformly maintain the spray speed of nozzle in the width direction, thereby stably manufacturing a strip with the constant thickness in the width and length direction. CONSTITUTION: A nozzle apparatus for uniformly spraying molten steel (100) includes a nozzle main body (110), a nozzle tip (200), and a guide member (300). The nozzle tip is formed at the bottom end of main body, and sprays, to the outside of nozzle main body, molten steel that is injected into a passage. The guide member is provided in the passage, and guides the flow of molten steel so as to inject the molten steel into the nozzle tip at the stable speed. The lower portion of guide member has a curved section (310) that has the curvature of predetermined size, and stably maintains the cross-section of passage. A space portion is formed between the bottom edge of curved portion and the top edge of nozzle tip for absorbing the micro-turbulence which is generated in the edge portion of passage.
