  • a target temperature may be preferably in the range of 200 °C to 350 °C, and may be more preferably in the range of 250 °C to 320 °C (for example, 280 °C may be determined as a target).
  • the target temperature may be in the range of 150 °C to 250 °C (for example, 180 °C may be set as the target temperature), which may vary depending on whether a subject for generating an aerosol is glycerin, a tobacco body, a tobacco body to which a liquid composition, such as glycerin, is absorbed, or a nicotine liquid.
  • the target temperature of a heating element needs to be determined in advance in consideration of the fact that an excessively high temperature of the generated aerosol may cause discomfort to the user or risk of burns cause excessive formation of an aerosol, making it difficult to puff several times, although cooling of the aerosol during a puffing process is taken into account. Also, for the above reason, an upper limit of the target temperature of the heating element is limited as mentioned above.
  • a temperature at which the generated aerosol passes through the cooling tube rod 20 and the filter rod 10 may be measured as a mouth end temperature, and in order not to discomfort the user, the temperature of the aerosol needs to be below 50 °C, preferably, 45 °C or lower.
  • a preferred aerosol mouth end temperature ranges from 25 to 45 °C, and a more preferred aerosol mouth end temperature ranges from 30 °C to 40 °C.
  • the aerosol medium rod 30, the tobacco body rod 41 or the nicotine rod 42 are provided in a length direction of the smoking article (in some cases, the aerosol medium rod 30 may be located upstream or downstream), and as described above, since the target temperature of the aerosol medium rod 30, the target temperature of the tobacco rod 41, and the target temperature of the nicotine rod 42 are different from each other, It is preferable that an independent heater capable of heating the aerosol medium rod 30 and the tobacco body rod 41 or the nicotine rod 42 in response to each target temperature is provided in the heating space of the heating device.
  • a heater e.g., a resistive heating heater
