The fifth wrapper 245 may be internally added with a predetermined material. Here, an example of a certain material may be silicon, but is not limited thereto. For example, silicone may have properties such as heat resistance with little change depending on temperature, oxidation resistance without oxidation, resistance to various chemicals, water repellency, or electrical insulation. However, even if it is not silicon, any material having the above-mentioned characteristics can be applied or coated on the fifth wrapper 245 without limitation.

The fifth wrapper 245 can prevent the stick 20 from burning. For example, when the tobacco rod 21 is heated by the heater 110, there is a possibility that the stick 20 may burn. Specifically, when the temperature rises above the ignition point of any one of the materials included in the tobacco rod 21, the stick 20 may burn. Even in this case, since the fifth wrapper 245 includes a non-combustible material, combustion of the stick 20 can be prevented.

Additionally, the fifth wrapper 245 can prevent the main body 100 from being contaminated by substances generated from the stick 20. Liquid substances may be created within the stick 20 by the user's puff. For example, as the aerosol generated from the stick 20 is cooled by external air, liquid substances (eg, moisture, etc.) may be generated. As the fifth wrapper 245 wraps the stick 20, liquid substances generated within the stick 20 can be prevented from leaking out of the stick 20.

The tobacco load 21 may contain an aerosol-generating material. For example, the aerosol-generating material may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. Additionally, the tobacco rod 21 may contain other additives such as flavoring agents, humectants and/or organic acids. Additionally, a flavoring agent such as menthol or a moisturizer can be added to the tobacco rod 21 by spraying it on the tobacco rod 21 .

The tobacco rod 21 can be manufactured in various ways. For example, the tobacco rod 21 may be manufactured as a sheet. For example, the tobacco rod 21 may be manufactured as a strand.

As an example, the heat-conducting material surrounding the tobacco rod 21 can evenly distribute heat transferred to the tobacco rod 21 and improve the thermal conductivity applied to the tobacco rod 21. This may improve the taste of the tobacco. The heat-conducting material surrounding the tobacco rod 21 may function as a susceptor that is heated by an induction heater. At this time, although not shown in the drawing, the tobacco rod 21 may further include an additional susceptor in addition to the heat-conducting material surrounding the outside.
