Abstract

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).
