摘要：
To provide a glass roll capable of reliably preventing a glass film from breaking from an end surface of the glass film as an origin of breakage, a glass roll (1) is formed by winding a glass film (2) into a roll while superposing the glass film (2) on a protective sheet (3), the glass film (2) being formed by an overflow downdraw method to have a thickness of 1 μm or more and 200 μm or less, and to have each end surface in a width direction to form a cut surface cut by laser splitting.
