Abstract
Provided is an aerosol generation device that has few necessary structural elements and highly accurately detects shortage of an aerosol source. An aerosol generation devicethat comprises: a power sourcea storage partA that stores an aerosol source or an aerosol substrateB that holds an aerosol source; a loadthat has a temperature-variable electrical resistance value and, by generating heat due to supply of power from the power sourceatomizes aerosol source supplied from the storage partA or aerosol source held by the aerosol substrateB; a circuitthat electrically connects the power sourceand the loadand a control partthat, on the basis of a first voltage value that is the value of the voltage applied to the entire circuit and a second voltage value that is the value of the voltage applied to a part of the circuit at which the applied voltage changes as a result of changes in the temperature of the loaddetermines whether there is a shortage of aerosol source that can be supplied from the storage partA or aerosol source held by the aerosol substrateB.
