Abstract:
1. A multilayer printed wiring board, comprising: an insulation layer; a first interlayer resin insulation layer provided on the insulation layer; a layered capacitor section provided on the first interlayer resin insulation layer and having a high dielectric layer, and first and second layered electrodes that sandwich the high dielectric layer; a second interlayer resin insulation layer provided on the first interlayer resin insulation layer and the layered capacitor section; a metal thin-film layer provided over the layered capacitor section and on the second interlayer resin insulation layer; an outermost interlayer resin insulation layer provided on the second interlayer resin insulation layer and the metal thin-film layer; a mounting section provided on the outermost interlayer resin insulation layer and having first and second external terminals to mount a semiconductor element; and multiple via conductors penetrating each interlayer resin insulation layer, the via conductors comprising first via conductors that electrically connect the first layered electrode of the layered capacitor section to the first external terminals of the mounting section, and second via conductors that electrically connect the second layered electrode of the layered capacitor section to the second external terminals of the mounting section.
