Abstract
To manufacture a roll body (glass roll) of the glass film, which is subjected to a tension application, and is free from looseness, without adversely affecting the formation of the glass film and causing a problem such as cracks, provided is a method of manufacturing a glass roll (1), including: forming a glass film (2) by a downdraw method; and winding the formed glass film (2) into a roll while superposing the glass film (2) on a protective sheet (3), in which the glass film (2) and the protective sheet (3) are wound while higher tension in a winding direction is applied to the protective sheet (3) than to the glass film.
