Patent ID: 7149092

Claim:
A printed circuit board comprising: a first wiring layer on which a first conductive wiring is formed; a second wiring layer on which a second conductive wiring is formed, wherein the first and second wiring layers are electrically non-conductive, and sides of the first and second wiring layers on which the first and second conductive wirings are respectively formed do not face each other; a first conductive layer and a second conductive layer forming conductive regions are respectively laminated, with an insulating layer intervened therebetween, between the first wiring layer and the second wiring layer; a conductive first interlayer connecting member that connects the first conductive wiring of the first wiring layer and the second conductive wiring of the second wiring layer; and a conductive second interlayer connecting member that is connected to the conductive regions of the first conductive layer and the second conductive layer, is isolated from the first interlayer connecting member and surrounds the first interlayer connecting member, wherein the first conductive layer and the second conductive layer respectively include plural conductive regions of different potentials, with the second interlayer connecting member connecting conductive regions of substantially the same potential of the first conductive layer and the second conductive layer.
