1. A vaporizer cartridge as a component of an inhaler, comprising:
a hollow body with a continuous flow channel;
a storage tank for storing liquid, the storage tank having an access opening to the flow channel;
a vaporizer unit arranged in a region of the access opening and extending over an entirety of the access opening, the vaporizer unit comprising a wick member and a heating member, wherein the vaporizer unit is formed to be liquid-permeable in such a manner that liquid is conveyed at least initially in a capillary manner from the storage tank through the vaporizer unit in a direction of the flow channel;
wherein the wick member is formed from a plurality of granular grains which, as a result of their fill and/or formation, form microchannels which extend, for an establishment of a fluid connection between the storage tank and the flow channel, continuously from an entry side of the wick member to an exit side of the wick member;
an additional securing means configured and adapted to hold the wick member in a position in the region of the access opening in a manner which maintains the fluid connection;
wherein the securing means is of a physical and/or chemical type such that the plurality of granular grains are held in position by melting and/or precipitation-hardening processes;
wherein the plurality of granular grains of the wick member are fused directly with the hollow body; and
wherein at least a cover element is formed from the fused plurality of granular grains from at least one part of the wick member.
