Provided is a gas generating composition with a low combustion temperature, good ignition ability, and a high heat resistance. The gas generating composition includes: (a) a fuel; (b) an oxidizing agent including a basic metal nitrate; (c) a basic metal carbonate; and (d) a binder. The fuel of the component (a) includes melamine cyanurate (MC) and nitroguanidine (NQ), with a ratio (MC/NQ) of contents of MC and NQ being within a range of 0.3 to 1.5. The binder of the component (d) is one or two or more selected from: (d-1) starch, etherified starch, methyl cellulose, hydroxyethyl methyl cellulose, hydroxypropyl methyl cellulose, and hydroxyethyl cellulose; (d-2) poly(vinyl alcohol), polyvinyl ether, polyethylene oxide, polyvinyl pyrrolidone, and polyacrylamide; (d-3) guar gum, etherified guar gum, and tamarind gum. |
