To provide a long roll-like wound body having no ruggedness.

The roll-like wound body is obtained by winding the long and multilayer film, which includes a long optical film and a long protective film capable of being exfoliated from the long optical film, in a rolled state. A thickness fluctuation of the long optical film in the width direction is ±0.3% to ±3.0% of the mean value of the thicknesses thereof in the width direction and the three-dimensional center-line average roughness of the long protective film on the opposite surface thereof to the long optical film-side surface is 0.2-3.0 μm.
