Provided is an inhalation device that makes it possible to reduce the possibility of a user neglecting to replenish the remaining amounts of elements required for inhalation of an aerosol or a flavored aerosol. The inhalation device 100B comprises: a plurality of elements configured so as to contribute to the generation of an aerosol or a flavored aerosol by consuming stored capacity； a notification unit 108 configured so as to notify the person inhaling the aerosol； and a control unit 106 configured so as to cause the notification unit 108 to function when, for each of the plurality of elements, predetermined conditions set for the element including a requirement that the detected or estimated capacity be equal to or less than a threshold value for the element are satisfied. The conditions become more strict as the frequency with which work for returning to a state in which the plurality of elements have the capacity required for continuous generation of the aerosol is performed increases.
