A gas generator (1A) includes a housing including a lower shell (10) and an upper shell (20), an igniter (30), a gas generating agent (41), and a filter (50). The housing has a circumferential wall portion (12, 22) in a short, substantially cylindrical shape provided with a gas discharge opening (24) as well as a bottom plate portion (11) and a top plate portion (21) substantially in a disc shape closing axial end portions of the circumferential wall portion (12, 22). The filter (50) is formed from a stack structure made of a hollow, substantially cylindrical member and formed by winding hook metal. The housing further has, in a portion between the circumferential wall portion (22) and the top plate portion (21), an upper curved corner portion (23) which continues to each of these adjacent circumferential wall portion (22) and top plate portion (21) and is formed by abutment of an axial end portion of the filter (50) along a circumferential direction. |
