Aerosol generating article with internal susceptor

Abstract

An aerosol-generating article is provided that includes an aerosol-forming substrate for generating an inhalable aerosol upon heating. The aerosol-generating article (10) comprises a plurality of elements assembled in the form of a rod having a mouth end (70) and a distal end (80) upstream from the mouth end. The plurality of elements includes an aerosol-forming substrate (20) located at or toward the distal end of the rod. An elongated susceptor (25) is disposed substantially longitudinally within the rod and in thermal contact with the aerosol-forming substrate (20). The susceptor allows the article to be consumed using an electrically operated aerosol-generating device having an inductor.
