Abstract
In a process for a thin-plate form glass molded body, an upper mold part having a pressing surface is used together with a lower mold part having a setting surface arranged to be opposed to the pressing surface. A melted glass lump is pressed between the pressing surface and setting surface. The pressing is performed to set the temperature (° C.) of the thin-plate form glass molded body to a temperature of Tg−20 or higher, and lower than Tg, wherein Tg represents the glass transition point (° C.) of the glass, in a period of 0.8 second or less after the end of the pressing.
