The utility model discloses a partitioning temperature control type electronic cigarette heat-generating body, and belongs to the technical field of electronic cigarettes. The partitioning temperature control type electronic cigarette heat-generating body comprises a ceramic tube and a heat-generating substrate. The internal surface of the heat-generating substrate is provided with three thick-film resistors which are arranged in parallel. The heat-generating substrate with the thick-film resistors coils and wraps the surface layer of the ceramic tube. The two ends of any one thick-film resistor are electrically connected with electrodes respectively. The electrodes are arranged at the external surface of the heat-generating substrate. The electrodes are electrically connected with corresponding power wires. Compared with heat-generating bodies in the prior art, the beneficial effects of the partitioning temperature control type electronic cigarette heat-generating body are that the heat-generating source of the partitioning temperature control type electronic cigarette heat-generating body is the thick-film resistors printed on the internal surface of the heat-generating substrate so that heat generation is more uniform; the ceramic tube and the heat-generating substrate are sintered together so that the thick-film resistors acting as the heat-generating source do not fall off or loose from the ceramic tube in the production process; and the three thick-film resistors are respectively independent, and heating can performed together or independently, i.e. temperature of each temperature area can be freely controlled.
