Abstract
To provide a control device for an aerosol inhalator capable of determining a residual amount of an aerosol source without being influenced by changes in temperature of a heater due to inhalation. The aerosol inhalator is configured so that a temperature, during supply of an electric power or during aerosol generation, of the load which atomizes an aerosol source stored in a reservoir or retained by an aerosol base using heat generated by supply of electric power become higher when an inhalation is performed, the control device includes a sensor for obtaining a first value relating to the temperature of the load, and a controller, in which the controller is configured to determine depletion or insufficiency of the aerosol source in the reservoir or the aerosol base based on a comparison between a second value based on the first value and a threshold (E), the threshold is a value obtained by adding a positive first predefined value to the second value when a first condition that a residual amount of the aerosol source in the reservoir or the aerosol base is sufficient and the aerosol is being generated in the load is satisfied, and the inhalation is not performed, in a case where the first value is increased when the temperature of the load is increased, and the threshold is a value obtained by subtracting the positive first predefined value from the second value when the first condition is satisfied and the inhalation is not performed, in a case where the first value is decreased when the temperature of the load is increased.
