Claim:
1. A high-frequency signal transmission line comprising: a dielectric element assembly including a plurality of dielectric layers stacked on each other in a direction of lamination and extending in a predetermined direction; a signal line provided in the dielectric element assembly and extending in the predetermined direction; a first ground conductor provided on one side in the direction of lamination relative to the signal line; a second ground conductor provided on the other side in the direction of lamination relative to the signal line; and a first interlayer connecting conductor connecting together the first ground conductor and the second ground conductor, the first interlayer connecting conductor being provided in the dielectric element assembly on one side relative to a center in a width direction of the dielectric element assembly, the width direction being perpendicular or substantially perpendicular to the predetermined direction and to the direction of lamination; wherein the dielectric element assembly includes a first region in which the first interlayer connecting conductor is provided and in which no interlayer connecting conductors are provided on the other side relative to the center in the width direction, and a second region in which no interlayer connecting conductors are provided; in the first region, a portion of the signal line in a section that includes the first interlayer connecting conductor is positioned on the other side in the width direction relative to the center in the width direction of the dielectric element assembly; and in the second region, the signal line includes a portion that is positioned to overlap with the center in the width direction of the dielectric element assembly.
