Abstract

A method of manufacturing a glass sheet according to the present invention comprises the steps of creating split flows of molten glass in a forming body 10 and causing the molten glass to flow down, subsequently merging the flows at a merging point to form a glass sheet G and causing the glass sheet to flow downward in the vertical direction. In this method of manufacturing a glass sheet, a partition member 20 is disposed facing the glass sheet G in the vicinity of a location below the forming body 10, and a facing surface of the partition member 20 is shaped so as to correspond to a sheet thickness variation of the glass sheet G, so that a gap between the glass sheet G and the partition member 20 is substantially uniform.
