ABSTRACT:
In order to provide a method of manufacturing a glass panel which, in time of a baking process, restrains an internal stress generated in both of glass plates (1, 2) to prevent a decline in strength, and restrains inorganic and organic substances remaining within a void (V) defined between the glass plates (1, 2) to prevent deterioration in quality, a method of manufacturing a glass panel comprises the steps of executing a joining process for joining the pair of glass plates (1, 2) opposed to each other across the void (V) at peripheries thereof by using a low melting point glass (4) in a melted condition, executing a baking process for suctioning gas from said void (V) through a suction portion disposed in said glass plates while heating said void (V) defined between the glass plates (1, 2), and sealing said suction portion to seal said void (V), wherein the gas is suctioned from said void (V) with said low melting point glass (4) being in a softened condition in which a coefficient of viscosity thereof is 1010Pascal seconds (Pa·s) or less when said baking process is executed.
