摘要： A gas generator that eliminates work for welding-fixing a holder to a housing and subjecting the holder to an excess processing, which can be easily manufactured at low cost, and a method for manufacturing the gas generator. The gas generator includes an approximately short cylindrical housing including a bottomed member and a lid member, gas generants arranged in the housing to generate a high-temperature gas by combustion, a filter arranged in an inner circumference part of the housing so as to surround the gas generants in a diameter direction of the housing, an igniter energized from the outside to ignite, and a holder to which the igniter is fixed and that is fixed to the bottomed member so that the igniter is arranged coaxially with the housing. At least one of the holder and the bottomed member is clamped, and pressed and deformed in an axial direction of a hole so that the holder is fixed to the bottomed member.
