The gas generator includes a vessel having a pressurized gas accommodation chamber for accommodating pressurized gas therein, a partition that divides the pressurized gas accommodation chamber into two sections, and a through-hole which is defined in the partition, for communicating the two sections. The gas generator also includes two ignition units containing gas generating agents therein, and a gas release unit disposed in the pressurized gas accommodation chamber and having a rupturable gas sealing wall. A single ignition unit can be disposed in each section or two ignition units can be disposed in one of the two sections.
