An inhalation component generation device comprising: a load configured to vaporize or to atomize an inhalation component source by electric power from an electric power source , a notification unit , and a control unit configured to obtain a value representing a remaining amount of the electric power source, and to obtain an operation requesting signal to the load and to generate an instruction for operating the load ; wherein the control unit is configured to control the notification unit in a normal use mode and cause the notification unit to perform a first notification when the value representing the remaining amount of the electric power source is equal to or greater than a first threshold value; the control unit is configured to control the notification unit in a charge requesting mode and cause the notification unit to perform a second notification when the value representing the remaining amount of the electric power source is less than the first threshold value and equal to or greater than a second threshold value that is less than the first threshold value; the control unit is configured to control the notification unit in an abnormality notifying mode and cause the notification unit to perform a third notification when the value representing the remaining amount of the electric power source is less than the second threshold value; and the first notification, the second notification, and the third notification are different from each other; the inhalation component generation device being characterized in that the control unit is configured to automatically change the first threshold based on a value relating supply of electric power from the electric power source to the load . a load configured to vaporize or to atomize an inhalation component source by electric power from an electric power source , a notification unit , and a control unit configured to obtain a value representing a remaining amount of the electric power source, and to obtain an operation requesting signal to the load and to generate an instruction for operating the load ; wherein the control unit is configured to control the notification unit in a normal use mode and cause the notification unit to perform a first notification when the value representing the remaining amount of the electric power source is equal to or greater than a first threshold value; the control unit is configured to control the notification unit in a charge requesting mode and cause the notification unit to perform a second notification when the value representing the remaining amount of the electric power source is less than the first threshold value and equal to or greater than a second threshold value that is less than the first threshold value; the control unit is configured to control the notification unit in an abnormality notifying mode and cause the notification unit to perform a third notification when the value representing the remaining amount of the electric power source is less than the second threshold value; and the first notification, the second notification, and the third notification are different from each other; the inhalation component generation device being characterized in that the control unit is configured to automatically change the first threshold based on a value relating supply of electric power from the electric power source to the load . <EOS>
