Claim Text:
1. A printed circuit board, comprising: a core substrate; an electronic component device comprising an inductor component and a passive component forming a low pulse filter for an IC chip such that the low pulse filter is accommodated in a single opening portion formed in the core substrate; a wiring structure connecting the inductor component and the passive component in the electronic component device; a filler resin body filling a space formed between the core substrate and the electronic component device positioned in the opening portion of the core substrate; a first buildup layer comprising a first interlayer resin insulation layer formed on a first surface of the core substrate, a first conductive layer formed on the first interlayer resin insulation layer, and a first via conductor formed in the first interlayer resin insulation layer; and a second buildup layer comprising a second interlayer resin insulation layer formed on a second surface of the core substrate on an opposite side with respect to the first surface of the core substrate, a second conductive layer formed on the second interlayer resin insulation layer, and a second via conductor formed in the second interlayer resin insulation layer, wherein the wiring structure comprises a connection circuit portion formed on the first interlayer resin insulation layer and a plurality of connection via conductors formed through the first interlayer resin insulation layer and connected to the connection circuit portion such that a first connection via conductor of the connection via conductors is connected to an output electrode of the inductor component and a second connection via conductor of the connection via conductors is connected to a power source electrode of the passive component.
