An electrically heated aerosol-generating device is provided, including a heating assembly configured to heat an aerosol-forming substrate to generate an inhalable aerosol, the assembly including a heater and a heater mount, the heater being blade-shaped, including an electrically insulating heater substrate, an electrically resistive heating element supported by the heater substrate, and a through-hole through a thickness of the heater, the heater being insertable into the aerosol-forming substrate and having a length of about 10 mm to about 60 mm, a width of about 2 mm to about 10 mm, and a thickness of about 0.2 mm to about 1 mm, the mount including a moldable material molded around a portion of the heater and extending through the through-hole to couple the heater to the mount so the mount provides structural support to the heater and is configured to allow the heater to be disposed within the device.

Aerosol generating device with anchored heater

The invention relates to a planar heating element () comprising a PTC resistive structure (), which is arranged in a defined surface region () of a first surface () of a support substrate (), wherein electrical connection contacts () for connection to an electrical voltage source () are associated with the PTC resistive structure (), wherein the PTC resistive structure ()&#x2014;starting from the two electrical connection contacts ()&#x2014;has at least one internal conductive trace () and a parallel connected, external conductive trace (), wherein the internal conductive trace () has a greater resistance than the external conductive trace () and wherein the resistances of the internal conductive trace () and external conductive trace () are so sized that upon applying a voltage an essentially uniform temperature distribution is present within the defined surface region ().
