PROBLEM TO BE SOLVED: To provide an optical film roll having a good winding figure.SOLUTION: There is provided an optical film roll obtained by winding a multilayer film, which is obtained by sticking an optical film including an alicyclic structure-containing polymer and a protective film peelable form the optical film, in a rolled state. An arithmetic mean roughness Ra of the surface on the side opposite to the optical film of the protective film is 0.2 μm or more and 1.4 μm or less, and an average film thickness h in the width direction of the optical film, a film thickness hat the center in the width direction, a film thicknesses hand hin both end parts in the width direction, a film thickness hat an optional width position and an average film thickness hin the width direction in the range of the width position w±200 mm satisfy a predetermined relation. |
