Abstract: A heating assembly (120), an atomizer (10), and an electronic cigarette. The heating assembly (120) is used to atomize an e-liquid, and comprises a substate (121). The substate (121) is a porous ceramic. The substate (121) has a liquid guiding surface (121a) and an atomization surface (121b). The e-liquid enters the substate (121) via the liquid guiding surface (121a). A through-hole (121c) is provided on the substate (121). The through-hole (121c) extends from the liquid guiding surface (121a) and passes through to the atomization surface (121b). In the heating assembly (120), the through-hole (121c) is provided on the substate (121), such that when the heating assembly (120) acts as a heating component of the atomizer (10), a consumption of the e-liquid is not prone to form negative pressure in an e-liquid storage chamber (110). The e-liquid in the e-liquid storage chamber (110) continuously reaches the atomization surface (121b) of the substate (121), such that the atomizer (10) is less prone to generate a scorched smell resulting from dry burning, thereby improving user experience.
