  • the two electrodes preferably represent common electrodes for use as a heater in the aerosol generating device.
  • the consumable, in particular the heating layer is formed as a paste or dough. It is advantageous to provide the consumable in this shape at least because of the various storage possibilities.
  • the consumable in form of the dough is preferably provided or stored as a layer which is rolled up on itself similar to a spiral or a hyperbolic spiral. It is also possible to provide the consumable rolled on a bobbin.
