1. An aerosol generation device, comprising:
a power supply;
a load that generates heat upon receipt of electric power from the power supply and atomizes an aerosol source using the heat, and in which an electric resistance value of the load changes in response to a temperature;
a first circuit configured to cause the load to atomize the aerosol source;
a second circuit configured to detect a voltage that changes according to changes in temperature of the load, connected to the first circuit in parallel, and having an electric resistance value higher than an electric resistance value of the first circuit;
processing circuitry configured to acquire a value of a voltage applied to the second circuit and the load; and
a sensor configured to output a value of the voltage that changes according to the changes in the temperature of the load, wherein
the second circuit includes a known resistor that is connected in series with the load and has a known electric resistance value,
the sensor outputs a value of a voltage applied to the load or the known resistor as the value of the voltage that changes according to the changes in the temperature of the load,
the known resistor has an electric resistance value higher than an electric resistance value of the load, and
the sensor outputs the value of the voltage applied to the load.
