PROBLEM TO BE SOLVED: To propose a method of manufacturing a sheet roll efficiently producible, without causing a step height trace caused by a step height of a winding starting end part of a sheet and wrinkles caused by winding squeeze, and to provide the sheet roll provided by this manufacturing method.SOLUTION: This sheet roll is provided by winding the sheet on a cylindrical core. The sheet roll without causing wrinkles and without the step height trace, can be provided by arranging an elastic body of a thicker film than a thickness of the sheet along the sheet winding starting end part of the innermost layer of contacting with the cylindrical core on a surface of the cylindrical core. |
