Provided is an aerosol generation device that has few necessary structural elements and highly accurately detects shortage of an aerosol source. An aerosol generation device 100 that comprises: a power source 110; a storage part 116A that stores an aerosol source or an aerosol substrate 116B that holds an aerosol source; a load 132 that has a temperature-variable electrical resistance value and, by generating heat due to supply of power from the power source 110, atomizes aerosol source supplied from the storage part 116A or aerosol source held by the aerosol substrate 116B; a circuit 134 that electrically connects the power source 110 and the load 132; and a control part 106 that, 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 load 132, determines whether there is a shortage of aerosol source that can be supplied from the storage part 116A or aerosol source held by the aerosol substrate 116B.
