Abstract
Provided is a method of manufacturing a glass film, including a cleaving step (S5) of cleaving a band-like glass film (G1) conveyed in a predetermined conveying direction (X) through irradiation of the glass film (G1) with a laser beam (L). The cleaving step (S5) includes: a step of, while supporting a lower surface of the glass film (G1) by a surface plate (22) including an opening (25a), suctioning the glass film (G1) through the opening (25a); and a step of irradiating the glass film (G1) suctioned through the opening (25a) with the laser beam (L).
