PROBLEM TO BE SOLVED: To provide a gas generant composition capable of reducing the amount of a coolant filter and suppressing the generation of phosphorus oxide by lowering the combustion temperature. SOLUTION: (A) a fuel, (B) an oxidant containing a strontium compound, (C) a binder, (D) a phosphorus compound, (E) a strontium compound that does not function as an oxidant, / Or a gas generant composition that does not contain a strontium compound other than the component (E), and the ratio of the number of strontium atoms (Sr) to the number of phosphorus atoms (P) in the composition is represented by the following formula: Sr number A gas generant composition satisfying the relationship represented by / P number ≧ 1.67.
