1. An aerosol generation device, comprising:
a power supply;
a container configured to store an aerosol source or an aerosol base material that retains the aerosol source;
a load that generates heat upon receipt of electric power from the power supply and atomizes the aerosol source supplied from the container or retained in the aerosol base material using the heat, and in which an electric resistance value of the load changes in response to a temperature;
a circuit that electrically connects the power supply and the load; and
processing circuitry configured to
determine whether the aerosol source that is capable of being supplied from the container or is retained in the aerosol base material is insufficient in quantity, based on a first voltage value which is a value of a voltage applied to an entirety of the circuit and a second voltage value which is a value of a voltage applied to a portion in the circuit where the voltage to be applied changes according to changes in temperature of the load,
determine that the aerosol source is insufficient in quantity when the second voltage value satisfies a first condition a plurality of times while the first voltage value is controlled to be constant or when the electric resistance value of the load derived from the first voltage value and the second voltage value satisfies a second condition a plurality of times,
store the number of times that the first condition is satisfied or the number of times that the second condition is satisfied, and
decrease the number of times when the first condition is not satisfied or when the second condition is not satisfied.
