1. An aerosol delivery device comprising:
a heating member formed of a heating element conformed to a heater substrate, the heater substrate comprising a film or membrane underlying the heating element, wherein the heater substrate is configured as a truncated cone having a first end of a first size and a second end of greater size, and wherein the heating element comprises an electrically conductive ink printed on the heater substrate; and
a porous transport element configured for passage of an aerosol precursor composition along a length thereof, wherein the porous transport element has a first end in a heating arrangement with the heating member, wherein the truncated cone includes an interior passage therethrough, and wherein the first end of the porous transport element in the heating arrangement with the heating member is positioned at least partially within the interior passage of the truncated cone.
