To provide a manufacturing method for a glass panel in which a gap between glass panels can be held in a reduced pressure state for a long time without raising the baking temperature and lengthening a baking time, and to provide the glass panel manufactured by the method.

In the manufacturing method for the glass panel P, the peripheries of sheet glasses 1, 2 arranged so as to face to each other via the gap V are joined and sealed with a sealing material 4 for join, a baking treatment is executed where the gas in the gap V is vacuumed and removed from an exhaust hole 5 provided on the sheet glass 1 while heating, and then the exhaust hole 5 is sealed in a state that the pressure of the gap V is reduced and a desorbed gas is adsorbed by a getter. A non-evaporation type getter 6 is arranged in the vicinity of the exhaust hole 5, an evaporation type getter 7 is arranged in the gap V and the baking treatment is executed. The exhaust hole 5 is sealed, and then the evaporation type getter 7 is vaporized by a selective heating and evaporated onto the inside of the sheet glasses 1, 2.
