The invention discloses a porous ceramic atomization heating component of electronic cigarette. The porous ceramic atomization heating component of the electronic cigarette comprises a ceramic rod, a heating wire, an atomization pipe and a pedestal, the atomization pipe is vertically arranged on the pedestal, a notch is formed in the top or bottom of the atomization pipe, the ceramic rod is transversely arranged in the notch in the top or bottom, wherein the ceramic rod is made of oleophilic modified porous ceramic, the heating wire winds the surface of the ceramic rod, the heating wire is connected with a battery through a lead, a hollow sealing sleeve and a sealing ring are arranged at the notch of the atomization pipe, and an air hole communicated with the outside is opened in the pedestal. The porous ceramic atomization heating component of the electronic cigarette is capable of avoiding the disadvantages of dry burning, burnt smell and the like of a fiber rope, the oleophilic modified high-porosity porous ceramic is capable of more quickly conducting tobacco tar, the atomized smoke amount is large, and meanwhile, the PTC alloy heating wire can change the resistance thereof along with the temperature change so as to effectively regulate the temperature, and the smoke quality is more stable.
