Claim:
1. A high-frequency signal line comprising: a dielectric body including a first dielectric layer and one or more other dielectric layers laminated together in a lamination direction; a first signal line provided on a first main surface of the first dielectric layer, the first main surface being a main surface of the first dielectric layer located on one side of the first dielectric layer in the lamination direction; a second signal line provided on a second main surface of the first dielectric layer to face the first signal line with the first dielectric layer disposed therebetween, the second main surface being another main surface of the first dielectric layer located on another side of the first dielectric layer in the lamination direction, and the second signal line being electrically connected to the first signal line; a first ground conductor located on the one side of the first dielectric layer in the lamination direction farther from the first main surface than the first signal line; and a second ground conductor located on the another side of the first dielectric layer in the lamination direction farther from the second main surface than the second signal line; wherein the second ground conductor includes openings aligned along the second signal line; and a distance in the lamination direction between the first signal line and the first ground conductor is greater than a distance in the lamination direction between the second signal line and the second ground conductor.
