The present application provides an aerosol producing article and an aerosol generating system comprising the aerosol producing article. The aerosol producing article comprises: an aerosol-forming matrix and an external wrapping part; the external wrapping part comprises a first portion, and at least a part of the extension length of the first portion along the axial direction of the aerosol producing article coincides with the extension length of the aerosol-forming matrix; the outer surface of the first portion is provided with a plurality of holes penetrating through the external wrapping part. The above aerosol producing article has optimized infrared transmittance, and can promote the utilization efficiency of infrared rays when infrared heating is used.

A smoking article comprises a smoke generating section, having a tube wall and a tube cavity; the tube cavity being configured to contain the aerosol-forming matrix; an infrared radiation layer, being formed on at least part of the inner surface of the tube wall; the infrared radiation layer being configured to be heated by the smoking set to generate infrared rays and at least heat the aerosol-forming matrix by radiation. The infrared radiation layer is arranged on the inner surface of the tube wall, so that the infrared radiation layer is heated by the smoking set to generate infrared rays and at least heat the aerosol-forming matrix by radiation. The infrared rays have relatively long wavelength, and they can penetrate substance and “resonate” with molecules and atoms inside the substance and produce strong vibration and rotation, so that the temperature of the substance rises to achieve the purpose of heating.
