Patent ID: 7428155

Claim:
A printed wiring board comprising: a first insulating layer; a first electrically-conductive power supply layer formed on a surface of the first insulating layer; an island of a second electrically-conductive power supply layer contoured based on a projected image of an electronic circuit element, said second electrically-conductive power supply layer isolated from the first electrically-conductive power supply layer on the surface of the first insulating layer; a first electrically-conductive piece connecting the second electrically-conductive power supply layer to the first electrically-conductive power supply layer; a second insulating layer; a first electrically-conductive ground layer formed on a surface of the second insulating layer; an island of a second electrically-conductive ground layer contoured based on a projected image of the electronic circuit element, said second electrically-conductive ground layer isolated from the first electrically-conductive ground layer on the surface of the second insulating layer; a second electrically-conductive piece connecting the second electrically-conductive ground layer to the first electrically-conductive ground layer; and a capacitor connected to the first and second electrically-conductive pieces.
