Abstract

An aerosol-generating device is disclosed. The aerosol-generating device of the present disclosure includes a cartridge, which includes a chamber configure to store a liquid, a wick for receiving the liquid from the chamber, and a heater for heating the wick, a case, to which the cartridge is detachably coupled and which has an insertion space formed to accommodate insertion of a stick therein, a first circuit including the heater, and a second circuit for sensing the temperature of the heater. The second circuit includes a first resistor, which is disposed to be in contact with or adjacent to the heater to receive heat from the heater, wherein a resistance value of the first resistor is variable based on changes in the temperature thereof, a second resistor connected to the first resistor, and a sensor for acquiring the value of current applied to the second resistor.
