Abstract
The disclosure relates to a laminar evaporator, comprising a laminar electrical resistance heating element for pulse heating and evaporation of an inhalationally receivable material distributed or distributable on the heating element surface by means of an electric heating current flowing or flowable in a laminar manner with at least two electrical contacts and/or poles (2, 3) for introducing the filament current into the resistance heating element, where the resistance heating element has at least one slot-shaped recess (5) constricting the lines of flux (4) of the original electric field forming or formable between the poles (2, 3) and is superficially bonded with an open-celled porous structure holding or capable of holding the material.
