Provided is an inhaling device capable of reducing the possibility that user neglects to recover residual volume of units required for inhaling aerosol or aerosol added with fragrance.An inhaling device 100B includes a plurality of units configured to contribute to generation of aerosol or aerosol added with fragrance by consumption of accumulated volume, a notification unit 108 configured to perform notification to an inhaler of the aerosol, and a controller 106 configured to render the notification unit 108 to function when predetermined conditions set for the respective unit among the plurality of units are satisfied which include an necessary condition of the detected or estimated volume being equal to or lower than a threshold value set for the unit. Among the plurality of units, the frequency of performing an operation for bringing back a state having an volume required for continuously generating aerosol is higher, the conditions are more severe.本發明提供一種可減低使用者疏忽懈怠而未進行對於氣霧或加有香味的氣霧之吸嚐而言必要的單元的容量回復的可能性之吸嚐裝置。吸嚐裝置100B包含有：複數個單元，係構成為藉由消耗所蓄積的容量而有助於氣霧或加有香味之氣霧的產生；通知部108，係構成為對於氣霧的吸嚐者進行通知；以及控制部106，係構成為針對複數個單元中之各個單元，在針對該單元而設定的既定的條件得到滿足之情況，使前述通知部108發揮功能，其中，前述既定的條件係包含經偵測或推斷的容量在針對該單元而設定的閾值以下之要件；複數個單元之中回復到具有繼續產生氣霧所必要的容量的狀態之回復作業所進行的頻率越高者，該條件係越嚴格。
