摘要： Provided herein is an aerosol-generating article with enhanced vapor production. The aerosol-generating article according to some embodiments of the present disclosure includes a medium portion, a support structure which is disposed downstream of the medium portion and includes a first tubular structure having a first hollow formed therein, a cooling structure which is disposed downstream of the support structure and includes a second tubular structure having a second hollow formed therein, and a mouthpiece portion which is disposed downstream of the cooling structure. Here, an upstream end of the second tubular structure may abut a downstream end of the first tubular structure, and an average cross-sectional area of the second hollow may be larger than an average cross-sectional area of the first hollow. The cross-sectional area difference enhances an air flow diffusion effect, thereby eventually improving vapor production of the aerosol-generating article.
