The invention provides an electronic cigarette heating element, which comprises a base body, a heating element arranged on the base body, and a temperature sensor for detecting a surface temperature of the heating element, wherein a surface of the temperature sensor is provided with a protective heat conducting layer which is made of materials with temperature resistance of more than or equal to 250 DEG C, in a heating process of the heating element, a change amount X of a resistance value of the heating element is less than or equal to 50%, the change amount X of the resistance value is equalto |(R1-R2)/R1|, wherein R1 is the resistance value of the heating element after the temperature is increased, and R2 is the resistance value of the heating element at the room temperature of 25 DEGC. By the adoption of the electronic cigarette heating element, the temperature sensor is additionally arranged, so that a function of temperature controllability is achieved; and meanwhile, a high-temperature-resistant protective heat conducting layer is arranged, so that the heating element is prevented from being oxidized, friction of an adherend after the electronic cigarette is sucked is resisted, heat is better transferred, the heating effect of the heating element is improved, the heating temperature of smoke substances is controlled, and other toxic substances such as tar and the likeare prevented from being generated, thereby reducing harm of users for sucking electronic cigarettes, and ensuring the taste of the users for sucking the electronic cigarettes.
