Articles that generate aerosols and methods for manufacturing the same

Abstract

To provide an aerosol-generating article and a method of manufacturing the same that are capable of simultaneously improving satisfaction for a tobacco smoke taste and allowing low-cost manufacture.SOLUTION: An aerosol-generating article 100 includes: an aerosol-forming substrate portion 110, which includes shredded tobacco leaves and is configured to form aerosol when electrically heated by an aerosol generation device; and a mouthpiece portion 120, which is disposed downstream of the aerosol-forming substrate portion 110 to form a downstream end. Since the shredded tobacco leaves are less expensive than a reconstituted tobacco sheet, manufacturing cost of the aerosol-generating article may be reduced. In addition, unlike the reconstituted tobacco sheet, an amount of supplementary materials added to the shredded tobacco leaves is small, and thus off-flavors and off-tastes may be reduced, thereby improving user satisfaction for a tobacco smoke taste.SELECTED DRAWING: Figure 4

Claims
