Provided is an inhalation device that makes it possible to easily manage the remaining amounts of elements required for inhalation of an aerosol or a flavored aerosol.The inhalation device 100B comprises: a first element 126 and a second element 104 configured to contribute to generation of aerosol or aerosol imparted with flavor； a notifying part 108 configured to make a notification to an inhaler of the aerosol； and a controller 106 configured to cause the notifying part 108 to function in a first mode when a first capacity detected or estimated concerning the first element 126 is smaller than a first threshold and a second capacity detected or estimated concerning the second element 104 is equal to or larger than a second threshold and cause the notifying part 108 to function in a second mode different from the first mode when the first capacity is smaller than the first threshold and the second capacity is smaller than the second threshold. A frequency of performing work for returning the first element 126 to a state having a capacity necessary for continuously generating the aerosol is higher than the frequency concerning the second element 104.
