Patent ID: 8592687

Claim:
A signal line comprising: a laminated body including a plurality of insulator layers that include flexible material and are laminated on each other in a lamination direction; a linear signal line provided within the laminated body; a first ground conductor located above the signal line in the lamination direction within the laminated body and overlapping with the signal line in a planar view seen from the lamination direction; a second ground conductor located below the signal line in the lamination direction within the laminated body and overlapping with the signal line in the planar view seen from the lamination direction; and a via hole conductor connecting the first ground conductor and the second ground conductor to each other; wherein in the first ground conductor, a plurality of first opening portions are arranged along the signal line in the planar view seen from the lamination direction; and in the planar view seen from the lamination direction, the via hole conductor is provided between the first opening portions that are adjacent to each other, in a direction in which the signal line extends.
