A method for producing a metal sheet by use of a rolling mill including a roll stand, the metal sheet including, on each of an upper surface and a lower surface, one or more raised lines extending in a rolling direction, the method comprising:
- a preparing step of preparing grooved rolls, each of the grooved rolls including, in an outer peripheral surface, one or more grooves extending in a circumferential direction;
- an incorporating step of incorporating the grooved rolls in the roll stand as an upper roll and a lower roll, respectively;
- a forming step of rolling a workpiece by the rolling mill incorporating the grooved rolls, thereby forming the workpiece into a metal sheet with raised lines formed corresponding to the respective grooves of the grooved rolls.
