Summary:There are provided a method of manufacturing a surface light source device, and an apparatus for manufacturing a surface light source device using the method. According to the method, a light source body including a plurality of discharge spaces into which a discharge gas is injected is formed. Impurities being present in the discharge spaces are removed. A mercury gas is diffused into the discharge spaces. Then, the light source body is rapidly cooled from the temperature at which mercury exists in the gaseous state to a room temperature. The time for the mercury gas to be within the range of temperature at which the mercury gas is liquefied is significantly shortened, thereby preventing the liquefied mercury from moving to the region having a low temperature in the discharge spaces.
