Abstract
Provided is a method of manufacturing a glass sheet, which comprises a conveying step of conveying a glass sheet (G3) by holding an upper part of the glass sheet (G3) in a vertical posture. The conveying step comprises a first conveying step of conveying the glass sheet (G3) in a first direction along a direction perpendicular to a main surface of the glass sheet (G3), and a second conveying step of conveying the glass sheet (G3) in a second direction along a direction parallel to the main surface after the first conveying step. When a conveying direction of the glass sheet is changed from the first direction to the second direction, a lower part of the main surface (G3y) is supported by a roller (41) of a support portion (4) from a forward side in the conveying direction of the glass sheet (G3) conveyed in the first direction.
