A smoking article (2, 42) comprises: a combustible heat source (4) having opposed front (6) and rear (8) faces; an aerosol-forming substrate (10) downstream of the rear face (8) of the combustible heat source (4); and a single heat-conducting element (36) overlying a rear portion of the combustible heat source (4) and at least a front portion of the aerosol-forming substrate (10). The single heat-conducting element (36) comprises one or more layers of heat conductive material and the one or more layers of heat conductive material are radially separated from the combustible heat source (4) and the aerosol-forming substrate (10). The combustible heat source (4) is either a blind combustible heat source or the combustible heat source (4) is a non-blind combustible heat source and the smoking article (42) further comprises a non-combustible substantially air impermeable barrier (46) between the non-blind combustible heat source and one or more airflow channels (44) extending from the front face (6) to the rear face (8) of the non-blind combustible heat source. The single heat-conducting element comprises an outer layer of heat conductive material that is visible on the exterior of the smoking article. |
