Patent ID: 7772684

Claim:
An electronic device having wiring layers and electrically insulating layers stacked on a core board and establishing predetermined electrical conduction between the wiring layers through upper-lower side conducting vias provided in the electrically insulating layers, said electronic device comprising: a plurality of electronic component incorporating layers each having an insulating resin layer, an electronic component incorporated in said insulating resin layer, and an upper-lower side conducting through via provided in said insulating resin layer, one of said electronic component incorporating layers provided at least between one of said wiring layers and one of said electrically insulating layers or between said core board and said electrically insulating layer, wherein each of said electronic component incorporating layers comprises the insulating resin layer having 1) a first cutout portion including the electronic component therein, extending across the entire thickness of the electronic component incorporating layer, and having a thickness substantially the same as the electronic component inserted therein, and 2) a second cutout portion separate from the first cutout portion, including the upper-lower side conducting through via, and extending across the entire thickness of the electronic component incorporating layer, and said plurality of electronic component incorporating layers comprises, for at least the uppermost layer of the plurality of electronic component incorporating layers, a metal frame body surrounding said electronic component and said upper-lower side conducting via, and a metal cap having a flange portion fixed to said metal frame body of the uppermost-layer electronic component incorporating layer is provided, wherein said first cut portion does not expose a lower wiring layer of said wiring layers, and wherein a terminal portion of the electronic component faces an upper wiring layer of said wiring layers.
