Metal-gas-filled cell and method for manufacturing the same

A metal-gas-filled cell comprising:

• a cell main body comprising a first surface, a second surface, an injection port, and a gas generating portion;
• a first glass sheet attached to the first surface of the cell main body;
• a second glass sheet attached to the second surface of the cell main body;
• an optical chamber provided in at least one selected from the cell main body, the first glass sheet, and the second glass sheet, the optical chamber communicating with the gas generating portion;
• and
• a metal gas filling the optical chamber, wherein
• the gas generating portion comprises a plurality of grooves that are open to the first surface, and
• the injection port comprises a through hole extending from the first surface to the second surface, and communicates with the gas generating portion.
