A gas generator for air bag, which can be formed into a configuration that is longer in the axial direction, is advantageous not only from the viewpoint of manufacture but also from the viewpoint of the operational performance, and can be disposed suitably on a passenger's seat side. The gas generator for air bag includes a housing having a plurality of gas discharge ports and includes, within the housing, an igniter to be operated by an impact sensor upon sensing an impact, a gas generator to be ignited by the ignitor and burned to generate a combustion gas, and a filter for performing cooling of the combustion gas and/or catching of the combustion residues. The housing is substantially shaped like a cylinder which is longer in the axial direction and provided, in a circumferential wall thereof, with a plurality of gas discharge ports disposed in at least the axial direction. The filter is accommodated within the housing in such a way that an outer periphery thereof opposes an inner surface of the circumferential wall of the housing and forms a gap between the filter and the inner surface of the housing.
