1. An ultrasonic-based aerosol generation device with mutually separable cartridge and a control main body coupled, the ultrasonic-based aerosol generation device comprising:
a liquid reservoir configured to store a liquid aerosol-forming substrate;
a vibration element configured to provide ultrasonic vibrations to the stored liquid aerosol-forming substrate to form an aerosol; and
a porous member disposed apart from the vibration element and including a plurality of holes,
wherein the aerosol is formed as the stored liquid aerosol-forming substrate passes through the plurality of holes due to the provided ultrasonic vibrations,
wherein the vibration element comprises:
a vibration member configured to generate the ultrasonic vibrations; and
a vibration transmission member configured to transmit the generated ultrasonic vibration to the stored liquid aerosol-forming substrate,
wherein the vibration transmission member, the liquid reservoir, and the porous member are included in the cartridge,
wherein the vibration member and a controller configured to control the aerosol generation device are included in the control main body,
wherein the cartridge is replaceable, and
wherein the porous member is disposed facing and spaced apart from a vibrating surface of the vibration element.
