The present invention relates to a conductive carbon-ceramic composite, and a manufacturing method thereof. According to the present invention, the manufacturing method of the conductive carbon-ceramic composite comprises: a first step of preparing a raw material mixture by mixing a solvent, an organic substance soluble in the solvent, and ceramic powder; a second step of preparing a powdery raw material mixture by drying the raw material mixture; a third step of forming the powdery raw material mixture into a desired shape by inserting the powdery raw material mixture to a mold; and a fourth step of performing reduction sintering by sintering a molded product under a reducing atmosphere using inert gas. The conductive carbon-ceramic composite has electrical conductivity or semi-conductivity by carbon without using a carbon fiber, a carbon nanotube, a graphite powder, or the like.
