    Abstract: A multilayer printed wiring board including an insulation layer and a first interlayer resin insulation layer provided on the insulation layer. A layered capacitor section is provided on the first interlayer resin insulation layer and has a high dielectric layer and first and second layered electrodes that sandwich the high dielectric layer. Also included is a second interlayer resin insulation layer provided on the first interlayer resin insulation layer and the layered capacitor section, and 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 is provided on the second interlayer resin insulation layer and the metal thin-film layer, and a mounting section is provided on the outermost interlayer resin insulation layer and has first and second external terminals to mount a semiconductor element. Multiple via conductors penetrate each interlayer resin insulation layer. The via conductors include first via conductors that electrically connect the first layered electrode to the first external terminals, and second via conductors that electrically connect the second layered electrode to the second external terminals.
