Disclosed is a gas generating composition being stable and having a heating starting temperature of 170 to 220° C., which is of a low-temperature ignition type. The gas generating composition comprises ammonium perchlorate, a chlorine scavenger, and microcrystalline carbon powder. The chlorine scavenger is sodium nitrate or aluminium/magnesium mixed powder, and the microcrystalline carbon powder is activated carbon or charcoal. The gas generating composition preferably comprises 40 to 58% by weight of ammonium perchlorate, 30 to 41% by weight of the chlorine scavenger, and 1 to 30% by weight of the microcrystalline carbon powder.
