A printed circuit board which is thin and incorporates a large-capacitance capacitor function and a manufacturing method thereof. In one embodiment, the printed circuit board manufacturing method includes forming inner layer conductor circuits on a core substrate; forming a recess part on the core substrate; housing, in a recess part, a planar capacitor device that is not resin molded and has electrodes on the surfaces on a shared side; interposing the same between insulator resin and conductor metal foil to heat pressurize the same for forming a multi-layer plate; forming via holes for electrically connecting an outer layer conductor circuit to the electrodes of the capacitor device; forming a conductor layer on them; and forming the outer layer conductor circuits on the surfaces of the multi-layer plate.
