Summary:[PROBLEMS] To provide a roll, a rolling mill and rolling method capable of not only effectively correcting the plate crown of a material to be rolled but also reducing the edge drop and preventing a roll from damage caused by the increase of the local line pressure between the rolls. [MEANS FOR SOLVING PROBLEMS] A roll crown is formed by a continuous curve having a local maximum point and a local minimum value point where the central region held between the local maximum point and the local minimum point represents one function and the end region from the local maximum point to the nearer roll end represents another function having an inclination of steeper gradient (or having a radius decreasing more sharply toward the roll end) than that of the extension of the function in the central region.
