Abstract

It is provided an aerosol generation device (100), comprising a storage unit (116A) that stores an aerosol source or an aerosol base material that retains the aerosol source; a load (132) that generates heat upon receipt of power supply from a power source and atomizes the aerosol source, characterized in that physical properties of the load (132) change when the load (132) is heated at a temperature achievable only when depletion of the aerosol source in the storage unit (116A) or the aerosol base material occurs, and a value related to the physical properties of the load (132) in a steady state when the load (132) is cooled after the temperature of the load (132) increases up to a temperature achievable only when depletion of the aerosol source occurs is different from a value related to the physical properties of the load (132) in a steady state before the temperature of the load (132) increases; a sensor (112) that outputs a value related to the physical properties of the load (132); and a control unit (106) configured to determine whether the depletion has occurred, based on the output value of the sensor (112) in a steady state after a temperature of the load (132) increases up to a temperature or higher, the temperature allowing the aerosol source to be atomized.
