Abstract
A method of manufacturing a band-shaped glass includes forming, while being drawn downward, the band-shaped glass having a thickness of 300 μm or less except both edge portions in a width direction thereof, and then changing a conveying direction of the band-shaped glass to a lateral direction so that a front surface constitutes an upper surface. The band-shaped glass is introduced to a region for changing the conveying direction under a curved state in which the front surface side thereof is concave in the width direction. The band-shaped glass in the curved state satisfies a relationship of 0>δ≧−200 mm, where δ represents a maximum separation distance with respect to an imaginary straight line connecting both the edge portions of the band-shaped glass in the width direction, provided that the maximum separation distance is positive on the front surface side of the band-shaped glass.
