Patent ID: 8717772

Claim:
A printed circuit board comprising: a core substrate having an opening portion and comprising a resin material; a chip capacitor provided in the opening portion of the core substrate and comprising a dielectric body, a first electrode formed over the dielectric body, and a second electrode formed over the dielectric body such that the dielectric body is interposed between the first electrode and the second electrode; and a resin filler filling an entire gap of the opening portion between the core substrate and the chip capacitor in the opening portion of the core substrate, the resin filler including at least one filler selected from the group consisting of an inorganic filler, a ceramic filler and a metal filler, wherein the dielectric body of the chip capacitor comprises a ceramic body, the at least one filler is included in the resin filler such that a coefficient of thermal expansion of the resin filler is adjusted with respect to a coefficient of thermal expansion of the core substrate and a coefficient of thermal expansion of the capacitor, and the opening portion of the core substrate is a through hole opening extending through the core substrate.
