Patent ID: 8575496

Claim:
A multilayer printed wiring board, comprising: a layered capacitor section having a high dielectric layer and first and second layered electrodes sandwiching the high dielectric layer, where either the first or the second layered electrode is connected to a power-source line and the other layered electrode, which is not connected to the power-source line, is connected to a ground line to store a predetermined amount of electric charge; a metal thin-film layer provided over the layered capacitor section on an interlayer resin insulation layer, wherein the metal thin film layer is a power-source plane layer which maintains the same electrical potential as the layered electrode which is connected to the power-source line and is a continuous metal layer over the layered capacitor section except for ground lands; and a mounting section, provided over the metal thin-film layer on the interlayer resin insulation layer and configured to mount on a surface of the mounting section a semiconductor element electrically connected to the layered capacitor section through via holes.
