PROBLEM TO BE SOLVED: To provide a roll material production method in which a metal plate can be taken out one by one when blanked metal plates are laminated, and on which plural metal plates can be laminated in an aligned state.SOLUTION: A second finishing rolling process is performed in a roll material production process. Thereby, on a finished metal plate 1C, an inclination face 1a inclined upward is formed on only an upper face of an end edge. When the finished metal plates 1C are cut and laminated, a gap into which fluid f is blown is formed between a lower face of the uppermost finished metal plate 1C and the inclination face 1a of the finished metal plate 1C positioned on a second position from an upper side. |
