Aerosol-generating system comprising an internal heating element

Abstract

An aerosol-generating article (30) comprising: an aerosol-generating section (12), the aerosol-generating section (12) comprising: an aerosol-generating substrate (16) comprising a plurality of strands of aerosol-generating material, wherein the aerosol-generating substrate (16) has a density of between 100 milligrams per cubic centimetre and 700 milligrams per cubic centimetre; and an elongate internal heating element (18) located within the aerosol-generating substrate (16) in thermal contact with the plurality of strands of aerosol-generating material, wherein the internal heating element (18) is a susceptor element, wherein a ratio of an average width of the plurality of strands of aerosol-generating material to a width of the internal heating element (18) is between 0.05 and 4.
