Beschreibung
Zusammenfassung:	A heating element includes: a porous substrate; and a heating film having a first sub-film and a second sub-film stacked together, the first sub-film being located on a surface of the porous substrate and having a porous structure, the second sub-film being arranged on a side of the first sub-film away from the porous substrate. The second sub-film has a porous structure and a porosity of the second sub-film is less than a porosity of the first sub-film, or the second sub-film has a non-porous structure.
