Abstract
A glass roll includes a glass film formed by a downdraw method. The glass film is wound into a roll using a winding roller in a state in which front and back glass surfaces of the glass film formed in the forming operation are exposed, and during the winding operation, the glass film is superposed on a separable protective sheet. The protective sheet extends beyond both sides in a width direction of the glass film. The protective sheet can further be wound on an outer peripheral surface of the glass film by winding only the protective sheet from a trailing end of the glass film in a winding direction of the glass film.
