Abstract
A gas-generant-molded-article for air bags which is prepared by molding a gas generant composition into a cylindrical form containing an opening hole, wherein the relationship between the linear burning velocity r (mm/second) of said gas generant composition under a pressure of 70 kgf/cm2 and a thickness W (mm) of said molded article falls within a range represented by 0.005≦W/(2·r)≦0.3, with the linear burning velocity preferably falling within a range of from 1 to 12.5 mm/second.
