An aerosol generating device which is capable of generating an aerosol at an appropriate timing includes: a power source which supplies power in order to atomize an aerosol source and/or heat a flavor source; a sensor which outputs a measurement value for controlling the power supplied; and a controller which controls the power supplied on the basis of the measurement value. The controller controls a power supply amount from the power source to be a first value when the measured value is equal to or larger than a first threshold and smaller than a second threshold larger than the first threshold, and the power supply amount to be larger than the first value when the measured value is equal to or larger than the second threshold.
