In a gas generator, a plurality of gas discharge ports include a plurality of first gas discharge ports and one or a plurality of second gas discharge ports having an opening pressure higher than an opening pressure of the first gas discharge ports. An opening pressure of the first and second gas discharge ports are set, such that only the plurality of first gas discharge ports of the plurality of gas discharge ports are opened by the pressure of the gas when the igniter is actuated in a stand-alone state before the gas generator is incorporated into an airbag device, and among the plurality of gas discharge ports, the first gas discharge ports excluding some of the first gas discharge ports and at least some of the second gas discharge ports are opened by the pressure of the gas when the igniter is actuated in an assembled state.
