    Abstract: A method for manufacturing a roll for reducing rolling capable of suppressing the occurrence of fin flaws and edge flaws includes preparing a roll for reducing rolling for use on a three-roll type reducing-rolling mill. A ridge part (52) is formed in the adjacent portion between a caliber part and a flange part is rounded by cutting the ridge part (52) while rotating the roll for reducing rolling around the roll axis. In rounding the ridge part, in a ridge part region (RA52) within the range of 3.0 mm in a roll axis direction with the top of the ridge part (52) being the center, the average of radiuses of curvature measured at a 0.5 mm pitch is made in the range of 2.5 to 3.0 mm, and the difference between the maximum value and the minimum value of the radiuses of curvature is made at most 1.0 mm.
