PROBLEM TO BE SOLVED: To make the service life of a roll for continuous casting longer than that of conventional ones by minimizing the unevenness on the surface of a roll body even if the roll is repeatedly used. SOLUTION: The roll body 3 of the roll for continuous casting has a three-layered constitution, in which a 2nd layer 5 is formed on a 1st layer 4, and a 3rd layer 6 is formed on the 2nd layer 5. The 3rd layer 6 is formed of a thin-walled layer having no unevenness on its surface. On the surfaces of the 1st layer 4 and the 2nd layer 5, which are in contact with the inside of the 3rd layer 6 as a thin-walled layer, a plurality of annular hollow parts 7 are formed so as to cross the axial direction of a roll 1 for continuous casting at equal intervals.
