摘要： Provided herein are an aerosol-generating article having a flavor optimization function and an aerosol generation system including the same. The aerosol-generating article according to some embodiments of the present disclosure includes a filter portion, a medium portion which includes an aerosol-generating substrate and has a downstream end portion connected to an upstream end portion of the filter portion, and a wrapping structure which wraps around at least a portion of the filter portion or the medium portion. Here, the wrapping structure may include a heat conduction member or a heat conduction limiting member to appropriately control thermal energy delivered to the aerosol-generating substrate. Accordingly, the flavor and taste of tobacco smoke of the aerosol-generating article may be improved.

摘要： An aerosol-generating system includes a cigarette and an aerosol-generating apparatus. The cigarette includes a medium part including a tobacco material, a flavor unit including a flavoring material and a moisturizer, and a wrapper configured to wrap the medium part and the flavor unit. The aerosol-generating apparatus includes a first heater arranged on a portion corresponding to the medium part and configured to directly heat the medium part and indirectly heat the flavor unit by using heat transmitted through the wrapper, and a processor configured to control the first heater to make the aerosol-generating apparatus operate in a smoke-free mode in which no visible smoke is generated.
