A gas generator (1A) includes a housing including a lower shell (10) and an upper shell (20), an igniter (40), a gas generating agent (61), and a filter (70). The housing includes a bottom plate portion (11) to which the igniter (40) is assembled and a combustion chamber (60) accommodating the gas generating agent (61). The filter (70) is formed from a hollow cylindrical member and disposed in the housing so as to surround the combustion chamber (60) in a radial direction of the housing. The bottom plate portion (11) is provided with a positioning portion (38) formed from a resin-molded portion secured to the bottom plate portion (11), which is formed by adhering a fluid resin material to an inner surface and solidifying the same, and the positioning portion (38) abuts to an inner circumferential surface of an axial end portion of the filter (70) located on a side of the bottom plate portion (11). |
