PROBLEM TO BE SOLVED: To provide a laminated film which suppresses curling and facilitates positioning of a die in molding.SOLUTION: There is provided a laminated film 10 which is formed from a laminate of at least a support body 2 and a resin layer 1 formed from a resin, where an absolute value |B-A| that is a difference between a spectrum intensity ratio A obtained by dividing a spectrum intensity of a crystal portion of a resin measured by a Raman spectroscopy method in one direction of the resin layer 1 by a spectrum intensity of an amorphous portion and a spectrum intensity ratio B obtained by dividing the spectrum intensity of the crystal portion of the resin measured by a Raman spectroscopy method in another direction orthogonal to the one direction of the resin layer 1 by the spectrum intensity of the amorphous portion is in a range of 0.00 or more and 0.70 or less.SELECTED DRAWING: Figure 1 【課題】カールが抑制されており、成形時の金型の位置決めが容易な積層フィルムを提供する。【解決手段】少なくとも、支持体２と、樹脂により形成された樹脂層１との積層体から構成された積層フィルム１０であって、樹脂層１の一方向におけるラマン分光法で測定される樹脂の結晶部のスペクトル強度を非晶部のスペクトル強度で除して得られるスペクトル強度比Ａと、樹脂層１の一方向に直交する他方向におけるラマン分光法で測定される前記樹脂の結晶部のスペクトル強度を非晶部のスペクトル強度で除して得られるスペクトル強度比Ｂとの差の絶対値｜Ｂ−Ａ｜が、０．００以上０．７０以下の範囲にある、積層フィルム。【選択図】図１
