A heating assembly and an aerosol generating apparatus. The heating assembly (10) comprises a base body (11), an infrared layer (12), and a heating element (13); the base body (11) is used for accommodating an aerosol generating substrate; the infrared layer (12) is arranged on the surface of the base body (11) and/or the infrared layer (12), and is used for radiating infrared rays during heating, so as to heat and atomize the aerosol generating substrate; the heating element (13) is arranged on the base body (11) and is used for heating the infrared layer (12) in the process of being energized; and the heating element (13) has a resistance temperature coefficient characteristic and can be used as a temperature sensor. The heating assembly (10) is convenient to arrange, and is small in occupied space.
