Abstract (en)

[origin: EP3815559A1] An aerosol generating device and a heating assembly (2) thereof, comprising a heating member (21). The heating member (21) comprises a sheet-like substrate (212) and an electric conductive path (214) provided on an outer side of the sheet-like substrate (212). The electric conductive path (214) comprises a heat generating resistance portion (2141) and an electrical connection portion electrically connected to the heat generating resistance portion (2141). The heat generating resistance portion (2141) and the electrical connection portion are arranged along a length direction of the sheet-like substrate (212). Since no heating zone is provided between a second end where a mounting base (23) is located and a conductive electrode (2142), the possibility of generating harmful gas is reduced, and there can be more choices for the material of the mounting base, so that the cost is reduced. There is a large temperature gradient between the section corresponding to the heat generating resistance portion (2141) of the heating element into which the tobacco is inserted and the section corresponding to the conductive electrode (2142). The temperature of the section corresponding to the conductive electrode (2142) is relatively low, and the heating dissipation is small, which is conductive to the effective use of energy.
