  • Publication number: 20240284966
    Abstract: This non-combustion-heated stick 1 comprises: a tobacco section 10 that has an aerosol source 11 containing tobacco; a cooling section 20 that cools vapor, generated by heating the tobacco section 10 by means of a heat generating element, to produce an aerosol; and a filter section 30 through which the aerosol passes. The tobacco section 10 has a higher filling density of tobacco in a part closer to the heat generating element than in a part further away therefrom.
