PROBLEM TO BE SOLVED: To provide a method of obtaining a resin sheet of desired shape by cutting a resin sheet to be cut unwound from a roll, that is, a method of setting the resin sheet to a predetermined size after a tension applied to the resin sheet is eliminated.SOLUTION: A method of manufacturing a resin sheet includes a step A of unwinding a sheet to be cut from a roll, and a step B of forming a resin sheet of desired size by cutting the unwound sheet to be cut with a punching blade. The punching blade includes a cutting edge X for cutting the sheet to be cut in the direction perpendicular to the unwinding direction of the sheet to be cut, and a rectangular cutting edge Y opening to the upstream side or downstream side in the sheet unwinding direction. |
