PROBLEM TO BE SOLVED: To provide the film roll wounded with a film having a molecular structure with small unevenness and a method for manufacturing the same.SOLUTION: A deviation (dCE) of a peak area in a longitudinal direction of an energy position 4.95 ± 0.25 eV of a vibrator in a C region and an E region of the film roll according to the present invention measured by an ellipsometer is 0.001 or more to 0.150 or less, wherein the C region is a square region of 50 mm (longer direction)×50 mm (a width direction) having a center of gravity at an arbitrary point (C1) on a straight line parallel to a longitudinal direction bisecting the film, and the E region is on a straight line drawn from C1 in parallel with a width direction and is the square area of 50 mm (longer direction)×50 mm (width direction) having the center of gravity at the point (E1) at which a distance from an arbitrarily selected end portion in the width direction is 500 mm.SELECTED DRAWING: Figure 1 【課題】 本発明は、分子構造のムラが小さいフィルムを巻いたフィルムロール及びその製造方法を提供することをその課題とする。【解決手段】 エリプソメーターにより測定した、Ｃ領域とＥ領域における振動子のエネルギー位置４．９５±０．２５ｅＶの長手方向のピーク面積のばらつき（ｄＣＥ）が、０．００１以上０．１５０以下であることを特徴とする、フィルムロール。Ｃ領域：フィルムを二等分する長手方向と平行な直線上の任意の点（Ｃ１）を重心とする、５０ｍｍ（長手方向）×５０ｍｍ（幅方向）の正方形領域Ｅ領域：Ｃ１から幅方向と平行に引いた直線上にあり、かつ任意に選択した一方の幅方向端部との距離が５００ｍｍである点（Ｅ１）を重心とする、５０ｍｍ（長手方向）×５０ｍｍ（幅方向）の正方形領域【選択図】図１
