Abstract
A sheet roll comprises two glass films and a coupling portion, wherein end portions of the glass films are coupled together via the coupling portion and the coupled glass films are rolled into a roll shape. The coupling portion is a sheet-like coupling member formed of a resin film and placed on the end portions of the two glass films in a rolling direction so as to span therebetween. The sheet-like coupling member includes wide joint portions joined respectively to the end portions of the two glass films, and a necked portion which is narrower than the wide joint portions and is formed at a middle portion of the sheet-like coupling member in the rolling direction.
