1. A heated aerosol-generating article, the heated aerosol-generating article having an outlet end and a distal end, the heated aerosol-generating article comprising:
a heat diffuser at the distal end of the heated aerosol-generating article, the heat diffuser defining a cavity configured to receive an electric heating element; and
an aerosol-forming substrate configured to be entirely between the heat diffuser and the cavity of the heat diffuser and the outlet end of the heated aerosol-generating article in a longitudinal direction of the heated aerosol-generating article such that at least a portion of the heat diffuser is between the cavity and the aerosol-forming substrate in the longitudinal direction,
wherein the heat diffuser includes a non-combustible porous body configured to absorb heat, such that the heat diffuser is configured to heat air drawn through the heated aerosol-generating article from the distal end to the outlet end.
