Provided is a gas generator including a housing including a top plate, a bottom plate, and a peripheral wall, the bottom plate being axially opposite the top plate, and the peripheral wall including a gas discharge port and being located between the top plate and the bottom plate. In the gas generator, an internal space of the housing is separated into a first combustion chamber and a second combustion chamber by a partition wall axially and radially partitioning the internal space of the housing, the first combustion chamber being formed to accommodate a first gas generating agent and being on the top plate side, and the second combustion chamber being formed to accommodate a second gas generating agent and being on the bottom plate side. A first igniter and a second igniter are disposed at the bottom plate, the first igniter being configured to burn the first gas generating agent, and the second igniter being configured to burn the second gas generating agent. The partition wall includes a cylindrical portion and an annular portion, the cylindrical portion being formed to surround the first igniter and include a communication hole for making the first combustion chamber and the second combustion chamber to communicate with each other, and the annular portion being formed extend radially outward from a second opening on the top plate side of the cylindrical portion. A first opening of the cylindrical portion axially opposite the second opening is in contact with the first igniter, and an outer periphery of the annular portion is in contact with the peripheral wall of the housing, and, thereby, the first combustion chamber and the second combustion chamber are separated from each other.
