Abstract
Provided is an aerosol generation device that can more accurately detect shortage of an aerosol source after a cartridge has been replaced. An aerosol generation deviceA that comprises: a power source; a loadthat has temperature-resistance value characteristics, has a temperature-variable electrical resistance value, and atomizes an aerosol source by generating heat due to supply of power from the power source; memorythat stores the temperature-resistance value characteristics; a sensorthat outputs a value that is related to the resistance value of the load; and a control partthat, on the basis of the correspondence between the output value from the sensorand an estimated value for the temperature of the loadthat corresponds to the output value, calibrates the stored temperature-resistance value characteristics.
