Abstract: To provide a mechanism that makes it possible to further improve the quality of the inhalation experience provided by a flavor component generation device, a flavor component generation control device for controlling a flavor component generation device includes an attachment section that has detachably attached thereto an element configured so as to consume stored contents and thereby contribute to the generation of a gas to which a flavor component is added. The flavor component generation control device includes a controller that controls processing in which, for each of a plurality of the elements that have been attached to the attachment section in the past, identification information for the element is associated with a parameter indicating the consumption amount of the contents consumed in generation of the gas to which the flavor component is added. The result is stored in a storage.

Abstract: A power supply unit for an aerosol inhaler includes: a power supply configured to supply power to a load that atomizes an aerosol source; a temperature sensor configured to detect a temperature of the power supply; a controller; and a circuit board. The circuit board includes: a first surface; a second surface; a power supply layer in which a power supply path is formed; and a ground layer. The power supply layer and the ground layer are provided between the first surface and the second surface. The temperature sensor is mounted on the second surface, and at least one of the power supply path and the ground path is not formed in a region which overlaps the temperature sensor as viewed from a first direction, the first direction being a direction in which the first surface and the second surface are opposed to each other.

Abstract: This aerosol generation system is provided with a housing unit capable of housing a base material that contains an aerosol source, and a control unit that controls a temperature at which the aerosol source contained in the base material housed in the housing unit is heated. If a first puff in which a user inhales an aerosol generated from the aerosol source is performed, the control unit controls the temperature at which the aerosol source is heated, on the basis of information of a previous second puff.
