PROBLEM TO BE SOLVED: To provide a gas generating agent capable of purifying gas by reducing the combustion temperature of a gas generating composition, thereby reducing the amount of combustion residue and mist. A gas generant composition containing a fuel and an oxidant and further containing copper powder. The copper powder has an average particle size of 0.5 to 500 μm, a specific surface area according to the BET method of 100 to 20,000 cm 2 / g, and an electrolytic copper powder is preferable.
