A package substrate having embedded capacitor is provided. The package substrate includes a first core circuit board, at least one embedded capacitor, a second core circuit board and a dielectric layer. At least one metal layer is disposed on a surface of the first core circuit board and at least one first conductive through hole of the first core circuit board is connected to the metal layer. The embedded capacitor is embedded in the first core circuit board and connected to the metal layer. A wiring layer is disposed on a surface of the second core circuit board and at least one second conductive through hole of the second core circuit board is connected to the wiring layer. The dielectric layer is laminated between the first and the second core circuit boards.
