Abstract
Provided is an aerosol generation device that suppresses the effect that errors in the production of structural elements have on the accuracy with which shortage of an aerosol source is detected. An aerosol generation device that comprises: a power source; a loadthat has a temperature-variable electrical resistance value and atomizes an aerosol source by generating heat due to supply of power from the power source; a first circuitthat is used for the loadto atomize the aerosol source; a second circuitthat is connected in parallel to the first circuit, has a higher electrical resistance value than the first circuit, and is used to detect voltage that changes as a result of changes in the temperature of the load; an acquisition part that acquires the value of voltage that is applied to the second circuitand the load; and sensorsB,D that output the value of the voltage that changes as a result of changes in the temperature of the load
