A core substrate and a method of manufacturing the core substrate are disclosed. In accordance with an embodiment of the present invention, the core substrate includes an adhesive resin layer having a mineral filler added therein, a metal sheet, which is patterned and embedded in the adhesive resin layer, and an insulation layer, which is stacked on both surfaces of the adhesive resin layer. Since a through-hole is formed to correspond to the number of via holes in accordance with a higher density of a printed circuit board, no conventional land is required to be formed, thereby reducing the defect of eccentricity.

A metallic laminate and a method of manufacturing a core substrate using the same are disclosed. In accordance with an embodiment of the present invention, the metallic laminate includes an insulation material, a carrier layer, which is stacked on both surfaces of the insulation layer and in which the carrier layer is a metal, and a first metal foil, which is stacked on one surface of the carrier layer. By symmetrically forming two core substrates on either surface above and below the insulation material, each process of forming the core substrate can be performed at the same time in the shape of a pair of facing core substrates, thereby increasing the productivity by twice. The remaining insulation material having the carrier layer stacked thereon can be used as a base substrate that is used to manufacture a printed circuit board, thus preventing unnecessary waste of the insulation material.
