Specifically, the controller 116 controls supply of electric power to the stick heater 121-2 and the cartridge heater 121-1 by the power supply 111 on the basis of the substrate pair. In particular, the controller 116 controls operation of the stick heater 121-2 and operation of the cartridge heater 121-1 on the basis of the substrate pair attached to the inhaler device 100 (that is, used for generation of the aerosol). Compatibility between the flavor component contained in the stick-side aerosol and the flavor component contained in the stick-side aerosol may be good or may be poor. According to the above configuration, flavor of the aerosol which the user tastes can be made appropriate since control can be performed according to whether the compatibility is good or poor.

For example, the controller 116 compares the substrate pair attached to the inhaler device 100 with a substrate pair regarded as being appropriate stored in advance. This determination can be made by referring to a look-up table including information indicative of the substrate pair regarded as being appropriate. In a case where the substrate pair attached to the inhaler device 100 matches the substrate pair regarded as being appropriate stored in advance, the controller 116 determines that the substrate pair attached to the inhaler device 100 is appropriate.
  • the controller 116 determines that the substrate pair attached to the inhaler device 100 is inappropriate. In a case where the stick substrate 150 or the cartridge 120 is not attached, it is determined that the substrate pair attached to the inhaler device 100 is inappropriate.
  • this determination is also referred to as authentication processing. Determining that the substrate pair attached to the inhaler device 100 is appropriate is referred to as success of the authentication processing or authentication.

On the other hand, the controller 116 does not cause the stick heater 121-2 to perform heating in a case where the first predetermined condition is not satisfied in the heating permitted state. Similarly, the controller 116 causes the cartridge heater 121-1 to perform heating in a case where the second predetermined condition is satisfied in the heating permitted state. On the other hand, the controller 116 does not cause the cartridge heater 121-1 to perform heating in a case where the second predetermined condition is not satisfied in the heating permitted state.

According to this configuration, the authentication time can be included in the period of the holding down of the power button originally required for start of the preliminary heating. As a result, the authentication time elapses while the user is holding down the power button to start the preliminary heating, and therefore a user's waiting period can be shortened since the authentication processing has been already performed.
  • a result of the authentication processing is made invalid even in a case where the authentication processing has been completed.

According to this configuration, in a case where the substrate pair becomes inappropriate as a result of replacement of the stick substrate 150 or the cartridge 120 after start of the preliminary heating, generation of the aerosol is stopped. Therefore, it is possible to prevent the user from tasting the inappropriate flavor and to keep electric power consumption small.
