The present invention relates to a manufacturing method comprising a step for dispersing ceramic slurry, a step of separating the dispersed slurry by a centrifugation method, and a step of filtering the centrifuged slurry and a multi-layered ceramic condenser including a green sheet obtained from the ceramic slurry. According to the present invention, when centrifugal separation is applied to the manufacturing method for the slurry, the scattering of the particle size inside the slurry can be reduced, and coarse powder and flocculant can be removed. In addition, filtering efficiency can be improved by upgrading filter grades while filtering is performed. When the green sheet is molded by the manufactured slurry thereof, the surface roughness and compactness can be improved to be useful for manufacturing the thin green sheet. As a result, the scattering shown in the electric property of chips such as capacity, BDV, and etc. can be reduced by a dielectric material having an equal particle size.
