  • the decrease in the amount of aerosol generated due to the increase in the number of puffs can be offset by an increase in the amount of aerosol generated due to an increase in temperature caused by the releasing of the stick-type substrate 150, and a decrease in the amount of aerosol in the composition of the inhaled gas can be suppressed.
  • a deterioration in flavor over time after the heating starts, therefore, can be prevented, and the quality of the user's inhalation experience can be improved.
  • the series of processing performed by the apparatuses described herein may be achieved using software, hardware, or a combination of software and hardware.
  • Programs constituting the software are stored in advance in storage media (non-transitory media) provided inside or outside the apparatuses.
  • Each of the programs is, when executed by a computer, for example, loaded into a RAM and executed by a processor such as a CPU.
  • the storage media are, for example, magnetic disks, optical discs, magneto-optical disks, flash memories, or the like.
  • the computer programs may be distributed over a network, for example, without using storage media, instead.
