In the present embodiment, the aerosol generating device includes a load and a control unit. The load heats the aerosol-generating article including the aerosol substrate holding or carrying at least one of the aerosol source and the flavor source, using the power supplied from the power source. The control unit controls electric power supplied from the power supply to the load by dividing it into a plurality of phases for executing different control modes.在本實施形態中，霧氣產生裝置係具備有負載及控制部。負載係使用從電源供給來的電力，對包含有霧氣基材之霧氣產生物品進行加熱，該霧氣基材係保持或擔持有霧氣源及香味源的至少其中一者。控制部係控制從電源供給至負載之電力。控制部係將從電源供給至負載之電力分成執行不同之控制模式之複數個階段來進行控制。
