PROBLEM TO BE SOLVED: To provide a gas generating agent for an air bag inflator in which CO generation amount is suppressed. SOLUTION: A fuel, an oxidant, a binder and an additive, wherein the additive is one or two selected from complex basic carbonates represented by the following general formula (I) or (II) A gas generating composition as described above. M 1 + M 2 3+ CO 3 (OH) 2 (I), M 3 2+ M 4 2+ CO 3 (OH) 2 (II) (In formula (I), M 1 + represents H + , Li + , Na + , K + or NH 4+ ; M 2 3+ represents Al 3+ , Fe 3+ , Cr 3+ , Co 3+ , In 3+ , Bi 3+ , Sb 3+ , B 3+ , Sc 3+ or Ga 3+ ; in formula (II), M 3 2+ and M 4 2+ are different from each other, and Cu 2+ , Zn 2+ , Co 2+ , Ni 2+ , Mg 2+ , Mn 2+ , Fe 2+ or Be 2+ .
