Definitions

  • the following description relates to a method for manufacturing a combustible heat source for a smoking article, a combustible heat source manufactured by the manufacturing method, and a smoking article comprising the combustible heat source.
  • a number of smoking articles which are heated rather than combusted have recently been proposed. Unlike conventional smoking articles, these non-combustion type smoking articles are used by sucking an aerosol generated by heating the smoking article medium without burning the smoking article medium. As one of these types of heating-type smoking articles, there is a smoking article product to which a carbon heat source is applied.
  • a smoking article to which the carbon heat source is applied generates an aerosol by heat transfer from the carbon heat source to a smoking article medium located downstream of the carbon heat source.
  • the smoking article to which the carbon heat source is applied has a smoking form similar to that of a traditional smoking article, unlike general heating-type electronic smoking articles using a dedicated device, so that consumers' smoking convenience and satisfaction can be expected to be improved.
