Patent ID: 8114714

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 via provided in said insulating resin layer, said electronic component incorporating layer provided at least between one of said wiring layers and one of said electrically insulating layers and/or between said core board and said electrically insulating layer, wherein each of said electronic component incorporating layers is formed by placing the electronic component on a lower layer and directly forming on said lower layer the insulating resin layer having the upper-lower side conducting via so as to incorporate said electronic component therein, and at least the uppermost-layer electronic component incorporating layer of said plurality of electronic component incorporating layers comprises 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.
