Abstract:
A glass roll reliably prevents a glass film from breaking from an end surface of the glass film as an origin of breakage. The glass roll is formed by winding the glass film into a roll while superposing the glass film on a protective sheet. The glass film is formed by an overflow downdraw method to have a thickness of 1 μm or more and 200 μm or less, and has each end surface in a width direction formed as a cut surface cut by laser splitting.
