1. A substrate portion for use in an aerosol source member, said substrate portion comprising:
a series of overlapping layers of a composite substrate sheet, the composite substrate sheet comprising:
a non-woven web at least partially formed from regenerated cellulose fibers;
a plurality of conductive threads integrated into the non-woven web; and
a coating that includes a fibrous material and an aerosol precursor composition,
wherein the plurality of conductive threads are first arranged linearly and parallel, wherein the plurality of conductive threads is substantially aligned with a longitudinal direction of the non-woven web, and wherein the composite substrate sheet is subsequently overlapped into the series of overlapping layers.
