1. An aerosol generating device comprising:
a battery;
a first cartridge comprising a first material being a solid material, which comprises nicotine, and a first heater configured to heat the first material;
a second cartridge comprising a second material being a liquid material, which comprises an aerosol-forming agent, and a second heater configured to heat the second material; and
a controller configured to selectively control power supplied to the first heater and the second heater from the battery, according to a smoking mode,
wherein the controller is configured to:
control the power to allow the solid material and the liquid material to be heated in a first smoking mode to discharge a visible vapor, and control the power to allow only the solid material to be heated in a second smoking mode to discharge an invisible vapor,
wherein the first heater is a mesh heater and is disposed on one surface of the first cartridge, and
wherein, in the first smoking mode, vapor generated in the second cartridge is provided with nicotine by passing through the first cartridge and is discharged to the outside of the aerosol generating device.
