Abstract: The present disclosure relates to a cartridge for an aerosol delivery device such as a smoking article. The cartridge may include a base, a reservoir substrate, and an atomizer. The reservoir substrate may define a cavity therethrough. The atomizer may comprise a liquid transport element and a heating element extending at least partially about the liquid transport element. The atomizer may extend through the cavity through the reservoir substrate such that the heating element is positioned proximate an end of the reservoir substrate. Ends of the liquid transport element may extend to an opposing end of the reservoir substrate. A related method for assembling a cartridge for a smoking article is also provided.
