Abstract

A capsule for a heat-not-burn (HNB) aerosol-generating device may include a housing and a heater within the housing. The housing has interior surfaces defining a chamber configured to hold an aerosol-forming substrate. In addition, the housing has exterior surfaces constituting a first face, an opposing second face, and a side face of the capsule. The first face and the second face of the capsule are permeable to an aerosol. The heater has a first end section, an intermediate section, and a second end section. The first end section and the second end section of the heater may be external segments constituting parts of the side face of the capsule. The intermediate section of the heater is an internal segment disposed within the chamber of the housing.
