A gas generator for a vehicle occupant restraint system. The gas generator comprises a housing, a filter chamber, and a combustion chamber which is filled with solid propellant and which has an outflow end. The gas generator further comprises at least one igniter unit which has an igniter and ignites the solid propellant, and comprises at least one filter which adjoins the solid propellant at the outflow end and delimits the combustion chamber. The filter has a central part which at least in sections has the shape of a cone and tapers in a direction towards an interior of the combustion chamber. The solid propellant laterally adjoins the conical section.
