    Abstract: PROBLEM TO BE SOLVED: To provide a nozzle for continuous casting in which durability is enhanced by arranging a refractory layer of high performance, e.g., high corrosion resistance or high adhesion preventive properties, on the inner hole side, and to provide a method for manufacturing a nozzle for continuous casting in which push breaking of the outer circumferential side layer due to the difference in thermal expansion between the inner hole side layer and the outer circumferential side layer of body material is prevented, and exfoliation of the inner hole side layer in the way of casting is prevented. SOLUTION: The nozzle for continuous casting has such an integral structure as the boundary portion of the inner hole side layer 2 and an intermediate layer 4 touches the boundary portion of the intermediate layer 4 and the outer circumferential side layer 3 directly wherein the bonding strength of the intermediate layer and the inner hole side layer and the outer circumferential side layer adjoining the intermediate layer is 0.01 to 1.5 Mpa in a 1,000°C non-oxidizing atmosphere, and a compression rate K(%) of the intermediate layer in the 1,000°C non-oxidizing atmosphere under the pressure of 2.5 Mpa is 10% to 80%.
