(54) CONTROL UNIT OF AEROSOL GENERATION DEVICE


(57) A control unit of an aerosol generation device includes a processing device configured to acquire a remaining amount of an aerosol source. When the remaining amount of the aerosol source is smaller than a threshold value, the processing device suppresses discharge from a power supply to an atomizer configured to atomize the aerosol source, and when the remaining amount of the aerosol source is equal to or greater than the threshold value, the processing device controls the discharge from the power supply to the atomizer so as to make an amount of the aerosol source to be atomized different, based on the remaining amount of the aerosol source.
