1. An evaporator comprising:
an electrical resistance heating element for pulse heating and evaporation of an inhalationally receivable material distributed or distributable on a surface of the electrical resistance heating element by an electric heating current flowing or flowable in a laminar manner with at least two electrical contacts or poles for introducing the electric heating current into the electrical resistance heating element,
wherein the electrical resistance heating element has at least one recess constricting lines of flux of an original electric field forming or formable between the at least two electrical contacts or poles,
and the electrical resistance heating element is in contact with an open-celled porous structure which can hold the material.
