Aerosol generating device and heater

A heater for heating a smokable material to generate aerosol for inhalation, comprising:

• a susceptor portion, being configured to be penetrated by a varying magnetic field to generate heat, and to heat the smokable material by heat conduction;
• and
• an infrared emission portion, being configured to be arranged next to the susceptor portion and being capable of receiving the heat of the susceptor portion, and being configured to radiate infrared rays to heat the smokable material when it is heated by the susceptor portion;
• a base, being configured in a tubular shape extending in an axial direction of the aerosol generating device and surrounding a cavity formed in the aerosol generating device and configured to receive the smokable material therein;
• wherein
• the infrared emission portion and the susceptor portion are sequentially arranged outside the base along a radial direction of the base.

• wherein the infrared emission portion is disposed closer to the smokable material than the susceptor portion when the smokable material is inserted into the aerosol generating device;
• the infrared emission portion is made from a material selected from a group consisting of amorphous carbon film, DLC film, graphene, carbon nanotubes, Fe2O3, Cr2O3, In2O3, La2O3, Co2O3, Ni2O3, Sb2O3, Sb2O5, TiO2, MnO2, CeO2, CuO, ZnO, MgO, CaO, MoO3, SiC, TiN, CrN, AlN and Si3N4.
