PROBLEM TO BE SOLVED: To provide an immersion nozzle for continuous casting and a continuous casting method with which clogging of the nozzle can stably be prevented even under wide operating condition. SOLUTION: An inner surface wall part in contact with molten steel, is constituted of a refractory having≤0.05% sulfur content and preferably, the refractory having carbon containing≤0.03% sulfur content in the carbon. A stable structure in this inner surface wall part is formed as a waterfall basin-like bottom part having 5 to 50 mm depth and two spouting holes facedly arranged to the just upper side wall part of the bottom part and 20 to 40 mm thickness at the side wall part arranging the spouting holes.
