摘要： 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.

In Formula (1), R1 and R2 may be each at least one group selected from a nitro group, a cyano group, an acyl group, a carboxyl group, an alkoxycarbonyl group, a haloalkyl group, a sulfo group, an alkylsulfonyl group, an halosulfonyl group, and a haloalkylsulfonyl group, or may be a group formed by R1 and R2 bonded to each other [—SO2-L-SO2—] (where L represents a haloalkylene group). The counter cation may be a radical cation represented by Formula (2), where R1 and R2 represent electron-withdrawing groups that may be bonded to each other to form a heterocycle, and R3 to R5 represent a hydrogen atom, a hydrocarbon group that may have a substituent, or a heterocyclic group that may have a substituent.
