A gas generator including a housing, an igniter disposed inside the housing, a combustion chamber accommodating the igniter, a gas discharge port provided in the housing, and a filter having a cylindrical shape and disposed between the combustion chamber and the gas discharge port. The filter is positioned inside the housing such that a portion of at least one end surface of two end surfaces in an axial direction of the filter is supported by contact, an outer area positioned outward in a radial direction of the portion that is supported by contact is adjacent to a predetermined space, and a predetermined outer peripheral area of an outer peripheral surface of the filter near the at least one end surface is supported by contact. According to such a configuration, it is possible to suppress a short path of combustion gas in a gas generator equipped with a filter.
