    • Provided is a glass roll (1) formed by rolling a glass film (2) around a roll core (4) under a state in which a resin film (3) is superposed on an outer peripheral surface side of the glass film (2). The resin film (3) is superposed on the outer peripheral surface side of the glass film (2) under a state in which tension of from 100 kPa to 1 GPa is applied to the resin film (3). The following relationships hold true: {(tg×Eg)/(tp×Ep)}×(tg/R)≦0.1, and 1×10−5≦tg/R≦1×10−3, where tg [m] represents a thickness of the glass film (2), Eg [Pa] represents a tensile modulus of elasticity of the glass film (2), tp [m] represents a thickness of the resin film (3), Ep [Pa] represents a tensile modulus of elasticity of the resin film (3), and R [m] represents an outer diameter of the roll core (4).
    • 提供一种玻璃辊(1),其通过在玻璃膜(2)的外周面侧叠置树脂膜(3)的状态下将玻璃膜(2)卷绕在卷芯(4)上而形成, 。 在树脂膜(3)上施加100kPa〜1GPa的张力的状态下,将树脂膜(3)重叠在玻璃膜(2)的外周面侧。 以下关系成立:{(tg×Eg)/(tp×Ep)}×(tg / R)≦̸ 0.1和1×10-5≦̸ tg / R≦̸ 1×10-3,其中tg [ ]表示玻璃膜(2)的厚度,Eg [Pa]表示玻璃膜(2)的拉伸弹性模量,tp [m]表示树脂膜(3)的厚度,Ep [Pa]表示 树脂膜(3)的拉伸弹性模量,R [m]表示辊芯(4)的外径。
