PROBLEM TO BE SOLVED: To provide a built-in capacitor designed for multilayer wiring board wiring boards which ensure flexibility in capacitors, particularly in thin capacitors which are to be incorporated into the insulating resin layer of the build-up layers, provides protection against damage due to a certain degree of stress and simplifies a process for incorporating the capacitor in the insulating resin layer of the build-up layers and a multilayer wiring board fabricated therewith.;SOLUTION: This capacitor is a built-in capacitor 1 intended for use by a multilayer wiring board and its metal-contained volume to the total volume of the capacitor 1 is 45 vol% or more but 95 vol% or less.;COPYRIGHT: (C)2007,JPO&INPIT
