Apparatus for manufacturing glass plate and method of manufacturing glass plate

Abstract

Provided is a thin glass plate manufacturing apparatus by: pouring a molten glass (G) into an overflow trough (2) formed in a top of a forming body (1); allowing the molten glass (G) which is overflown from the overflow trough (2) over a top planar portion (3) of the forming body (1) on each side of the overflow trough (2) to flow downward along an outer surface portion (4) having a substantially wedge-like shape of the forming body (1); and fusing and integrating the molten glass (G) at a lower end of the forming body (1), thereby forming a thin glass plate having a thickness equal to or less than 500 μm, in which a molten glass contact surface of at least the top planar portion (3) of an outer surface of the forming body (1) has a maximum height roughness (Rz) of equal to or less than 10 μm.

Dependencies are inferred from the claim text.
