A heating device, an atomizer and an electronic cigarette. The heating device comprises a heating member (530), a liquid guide member, and a base (532). The heating member (530) is provided therein with an airflow passage (5301) through which the airflow passes. The liquid guide member is used for absorbing and/or storing e-liquid to be atomized by the heating member (530). Both the heating member (53) and the liquid guide member are mounted in the base (532). The base (532) is made of a ceramic material and can retain a certain atomization temperature so that the smoking mouth feel each time has little difference, and moreover, dry burning caused by improper assembly is avoided from affecting the smoking mouth feel.
