1. An aerosol-generating system comprising:
a cartridge including,
a storage portion,
a heater assembly including,
a cap including,
a hollow body having a first cap opening and a second cap opening, the first cap opening being opposite the second cap opening, the cap being integrally formed, and
a holder including a holder opening, the holder configured to cover the first cap opening such that the holder opening superposes with at least a portion of the first cap opening, the cap and the holder being integrally formed,

a heating element, the heating element being a flat electrically conductive and fluid permeable heating element, the heating element configured to vaporise an aerosol-forming substrate, and the heating element mounted on the holder such that the heating element extends across the first cap opening, and the heating element including,
a mesh including at least two electrically conductive contact areas, each of the at least two electrically conductive contact areas positioned at an edge area of the heating element, the mesh including a first mesh section having a first mesh density and a second mesh section on an end of the first mesh section, the second mesh section having a second mesh density that is higher than the first mesh density, the first mesh section extending across the first cap opening,

a host material piece including a wicking material, the host material piece configured to retain the aerosol-forming substrate, at least a portion of the host material piece arranged in the hollow body between the first cap opening and the second cap opening, the host material piece at least partially in contact with the heating element, and

a retainer extending over the holder opening and along at least a portion of sides of the storage portion; and
a power source configured to supply power to the heating element.
