Abstract
There is disclosed a wiring board comprising a core substratea build-up layerformed on at least one side of main surfaces the core substrate, wherein a cavityfor accommodating a chip-type decoupling capacitoris formed in the build-up layerThe capacitorincludes electrode terminals on an upper surface thereof that are directly connected to a semiconductor component, and electrode terminals on a back surface of the capacitoris connected to a wiring conductor layeron a bottom surface of the cavityThis structure enables decoupling capacitor and the semiconductor componentto be connected with low resistance and low inductance.
