Abstract
A method for manufacturing a glass panel unit, which reduces the amount of a getter material to enable a gettering ability to be realized at a relatively low temperature less likely to cause damage. The method includes a step of producing a getter material by heating an unprocessed getter material at a temperature higher than a prescribed temperature Te; a step of producing a preassembled component including a first and second glass pane, a heat-fusible sealing material, an internal space, and a gas adsorbent containing the getter material, and an evacuation port; a step of forming a frame body hermetically bonding the first glass pane and the second glass pane together by melting the heat-fusible sealing material with heat; and a step of heating the gas adsorbent at the prescribed temperature Te while the internal space is evacuated by exhausting air in the internal space through the evacuation port.
