Circuit board

摘要

A structure (10) includes at least three conductors (111, 131, 151) that are opposed to each other, a penetration via (101) that penetrates the conductors (111, 131, 151), openings (112, 152) that are formed so as to surround the penetration via (101), and conductor elements (121, 141) that are located in layers other than the layers in which the conductors (111, 131, 151) are located and that are connected to the penetration via (101). The conductor element (121) larger than the opening (112) is opposed to the opening (112) and the conductor element (141) larger than the opening (152) is opposed to the opening (152).

1. A circuit board comprising: a plurality of structures, each of the structures having, at least three first conductors that are opposed to each other; penetration vias that penetrate each of the first conductors; an opening that is formed in at least one of the first conductors so as to surround the penetration via passing through the first conductors and that insulates the penetration via from the at least one first conductor; and a plurality of second conductors that are located in a plurality of layers other than layers in which the first conductors are located and that are connected to the penetration via, wherein the second conductors are transmission lines, where one ends thereof are connected to each of the penetration vias and the other ends thereof are open ends; and wherein the first conductors of neighboring ones of said plurality of structures are directly connected.
