A submerged entry nozzle for continuous casting is provided to prevent the generation and growth of attachments on an internal wall of a submerged entry nozzle by forming spiral guide grooves on an internal wall of a submerged entry nozzle functioning as a passage installed between a tundish and a mold to supply molten steel to the mold, thereby supplying rotary force to the molten steel, and to widen the discharge range of molten steel discharged from a submerged entry nozzle. A submerged entry nozzle(100) for continuous casting comprises an inlet port(120) and a discharge port(110) of molten steel for supplying molten steel from a tundish to the inside of a mold, wherein one or many spiral guide grooves(130) are formed on an internal wall of the submerged entry nozzle in the direction from the inlet port to the discharge port, and the space between the top and bottom of the guide grooves becomes narrower from the inlet port to the discharge port and the rotating direction of the guide groove is formed in the same direction as the rotating direction of molten steel when the molten steel moves.
