Abstract
An aerosol-forming article includes: an aerosol-forming substrate; a heating layer encircling a concave portion, the aerosol-forming substrate being arranged in the concave portion; and a cover layer covering at least a part of the heating layer and an opening of the concave portion. The aerosol-forming substrate is located between the heating layer and the cover layer. A through hole is provided at a position of the cover layer corresponding to the opening. The heating layer generates eddy currents in a magnetic field to generate heat so as to heat the aerosol-forming substrate to form aerosols.
