1. A heating device, configured for heating an aerosol generating substrate to volatilize at least one ingredient therein to form an aerosol, comprising a heating body, wherein the heating body comprises:
a base body, which is configured to have a chamber for receiving at least part of the aerosol generating substrate, a surface roughness of an outer surface of the chamber being greater than a surface roughness of an inner surface of the chamber; and
an infrared radiation coating, which is formed on the outer surface of the chamber and configured for generating infrared rays after a temperature rise and transmitting energy to the aerosol generating substrate received within the chamber at least in an infrared radiation manner, so that at least one ingredient in the aerosol generating substrate is volatilized to form an aerosol.
