摘要：
Provided is a glass roll utilizing a flanged roll core, and reliably inhibiting a glass film from breaking from an end portion in a width direction thereof as an origin of breakage. A glass roll (1) is formed by winding a glass film (4) and a cushion sheet (5), under a state of being superposed, around a roll core (3) including a flange (2) at each end portion thereof, in which an end portion in a width direction of the glass film (4) is separated from the flange (2) on each side in the width direction of the glass film (4), and the cushion sheet (5) is extended beyond the end portion in the width direction of the glass film (4) to the flange (2) side, to thereby form an extension portion (5a).
