1. An aerosol-forming article, comprising:
an aerosol-forming substrate;
a heating layer encircling at least one concave portion, the aerosol-forming substrate being arranged in the at least one concave portion; and
a cover layer covering at least a part of the heating layer and an opening of the at least one concave portion,
wherein the aerosol-forming substrate is located between the heating layer and the cover layer,
wherein a through hole is provided at a position of the cover layer corresponding to the opening,
wherein the heating layer is configured to generate eddy currents in a magnetic field to generate heat so as to heat the aerosol-forming substrate to form aerosols,
wherein the aerosol-forming substrate gathers to form a layered body,
wherein a bottom wall of the at least one concave portion is attached to a bottom surface of the aerosol-forming substrate, and
wherein a distance between a side wall of the at least one concave portion and a side surface of the aerosol-forming substrate ranges from 0.1 mm to 1.0 mm.
