1. A method for producing vaporizer units as a component of inhalers, comprising:
a) providing a flexible circuit board material with a plurality of sites for individual vaporizer units, the flexible circuit board material having an upper side and a lower side, the circuit board material having a passage opening at each of the plurality of sites, each opening connecting the upper and lower side;
b) providing and placing at least one heating element at each of the plurality of sites, each heating element having a circumferential edge region and a heating surface surrounded by the edge region, each of the at least one heating elements fully or partially covering the passage opening from the upper to the lower side of the circuit board portion at the respective site;
c) at least partial covering each site with a sealing material for the formation of a partial sheathing for each formed vaporizer unit, the sealing material being applied in such a manner that the sheathing formed from the sealing material covers at least the edge region of each heating element while keeping open the heating surface at least on an upper side of the flexible circuit board material, and at least an outer surface of the sheathing pointing away from the circuit board material and/or from the heating element forms sealing surfaces; and
forming circuit board portions from the flexible circuit board material, each circuit board portions each comprising at least two conductor paths and one of the passage openings.
