The inflator for air bags according to the present invention includes a cylindrical housing, an inner cylindrical member provided in the housing, a central cylindrical member provided in the inner cylindrical member, a gas generant packed in an annular space between the central cylindrical member and inner cylindrical member, and an ignition structure for igniting the gas generant. The ignition structure comprises booster charge provided in one end portion of the central cylindrical member, an igniter for igniting the booster charge, and a booster member provided in the part of the central portion of the central cylindrical member which is close to the booster charge, the booster member being made of a nonexplosive material so as to constitute a rod type member extending over substantially the whole length of the central cylindrical member. The ignition structure is capable of generating lengthwise uniform ignition energy.
