A submerged nozzle for high speed casting formed to obtain a flow rate corresponding with a casting slab drawing rate when supplying molten steel from a tundish to a casting mold is provided. A submerged nozzle(100) for high speed casting includes: a channel(110) which is formed in the submerged nozzle, and through which molten steel flows; an inner bottom(130) formed at a channel ending position of the submerged nozzle to block molten steel that flows directly to a lower side at which a casting mold is position; and a molten steel outlet(120) which is formed between the channel ending position and the inner bottom, and on which an inclined face(122) is formed, wherein the inclined face is inclined from the center of the submerged nozzle toward the casting mold, and the inclined face has a slope between 60 to 70 degrees of an angle when the length direction of the submerged nozzle is 0 degree of an angle. The inner bottom has a projecting part(132) formed at a position thereof where the inner bottom initially encounters the molten steel flowing along the channel.
