Aerosol-generating device and method of manufacturing the same

Abstract

An aerosol-generating device is disclosed. The aerosol-generating device includes a body and a hollow heater assembly disposed in the body and providing an insertion space with one side open. The heater assembly includes a heating element configured to heat the insertion space, an insulator forming multiple layers surrounding the outer side of the heating element in the radial direction of the insertion space, and a through-hole formed through the multiple layers. The through-hole is formed by overlapping holes formed in the multiple layers.

Dependencies are inferred from the claim text.
