A gas generator includes: a housing; an ignition unit disposed in the housing; a gas generating agent accommodated in a combustion chamber in the housing and that generates a combustion gas upon operation of the ignition unit; a discharge port provided in the housing and configured to discharge the generated combustion gas; and a filter disposed between the discharge port and the gas generating agent. The filter extends in an axial direction, at least an outer peripheral portion on one end surface of the filter in the axial direction is connected to an inner wall surface of the housing to surround the discharge port, a portion that is at least a part of an outer peripheral surface of the filter around an axis and extends over the entire circumference is an inflow portion of the combustion gas, and the inflow portion is in communication with the combustion chamber.
