The present invention relates to a ceramic atomizing wick. The ceramic atomizing wick comprises a power supply positive terminal, a power supply negative terminal, and a fixing mount. An air inlet is disposed and opened at an outer wall surface of the power supply positive terminal. A threaded hole is disposed and opened along an axial direction of the fixing mount, and a ceramic liquid guiding wick is partially installed in the threaded hole. An inner wall of the ceramic liquid guiding wick is in contact with an atomizing heating piece. The ceramic liquid guiding wick of the present invention is made of porous ceramics to have a characteristic of high-temperature resistance in order for being uneasy to produce scorched pastes thereon. The contact area of the ceramic liquid guiding wick with cigarette liquid is large, and the liquid guiding speed of the ceramic liquid guiding wick is fast.
