An aerosol generation device, comprising: a power supply; a load that generates heat upon receipt of electric power from the power supply and atomizes an aerosol source using the heat, and has a temperature-resistance value characteristic in which an electric resistance of the load value changes in response to a temperature; a memory that stores the temperature-resistance value characteristic; a sensor that outputs a value related to a resistance value of the load; and a control unit configured to control supply of electric power from the power supply to the load, to calibrate the stored temperature-resistance value characteristic based on correspondence between an output value of the sensor and an estimate of a temperature of the load corresponding to the output value, and to calibrate the stored temperature-resistance value characteristic based on correspondence between the output value of the sensor when electric power sufficient for aerosol generation is supplied to the load and a temperature causing the aerosol generation, and characterized in that the control unit is configured not to calibrate the stored temperature-resistance value characteristic when the output value of the sensor when the electric power sufficient for the aerosol generation is supplied to the load is equal to or higher than a threshold or when a change amount in the output value of the sensor when the predetermined electric power is supplied to the load is equal to or higher than a threshold. a power supply; a load that generates heat upon receipt of electric power from the power supply and atomizes an aerosol source using the heat, and has a temperature-resistance value characteristic in which an electric resistance of the load value changes in response to a temperature; a memory that stores the temperature-resistance value characteristic; a sensor that outputs a value related to a resistance value of the load; and a control unit configured to control supply of electric power from the power supply to the load, to calibrate the stored temperature-resistance value characteristic based on correspondence between an output value of the sensor and an estimate of a temperature of the load corresponding to the output value, and to calibrate the stored temperature-resistance value characteristic based on correspondence between the output value of the sensor when electric power sufficient for aerosol generation is supplied to the load and a temperature causing the aerosol generation, and characterized in that the control unit is configured not to calibrate the stored temperature-resistance value characteristic when the output value of the sensor when the electric power sufficient for the aerosol generation is supplied to the load is equal to or higher than a threshold or when a change amount in the output value of the sensor when the predetermined electric power is supplied to the load is equal to or higher than a threshold. to control supply of electric power from the power supply to the load, to calibrate the stored temperature-resistance value characteristic based on correspondence between an output value of the sensor and an estimate of a temperature of the load corresponding to the output value, and to calibrate the stored temperature-resistance value characteristic based on correspondence between the output value of the sensor when electric power sufficient for aerosol generation is supplied to the load and a temperature causing the aerosol generation, and characterized in that the control unit is configured not to calibrate the stored temperature-resistance value characteristic when the output value of the sensor when the electric power sufficient for the aerosol generation is supplied to the load is equal to or higher than a threshold or when a change amount in the output value of the sensor when the predetermined electric power is supplied to the load is equal to or higher than a threshold.
