Abstract
A high-frequency signal line includes a linear signal line and a first ground conductor provided at a dielectric body to extend along the dielectric body. The first ground conductor includes a first main surface and a second main surface opposed to each other in a direction of lamination. A strip-shaped protrusion extending along the signal line is provided on the second main surface of the first ground conductor.

A high-frequency signal line comprising:
- a linear dielectric body including flexible dielectric sheets laminated together in a direction of lamination;
- a signal line provided at the dielectric body to extend along the dielectric body;
- and
- a first ground conductor provided at the dielectric body to extend along the signal line, the first ground conductor including a first main surface and a second main surface opposed to each other in the direction of lamination;
- wherein
- a strip-shaped protrusion extending along the signal line is provided on the second main surface of the first ground conductor.

A method for manufacturing a high-frequency signal line comprising:
- a process of forming a dielectric body, the process including:
- a step of forming a linear signal line on a first dielectric layer;
- a step of forming a first ground conductor on a second dielectric layer;
- and
- a step of laminating and pressure-bonding the first dielectric layer and the second dielectric layer together such that the first ground conductor and the signal line face each other;
- wherein
- in the step of laminating and pressure-bonding the first dielectric layer and the second dielectric layer together, a strip-shaped protrusion protruding toward the signal line and extending along the signal line is formed on the first ground conductor by curving a portion of the first ground conductor to protrude toward the signal line in a section perpendicular or substantially perpendicular to the signal line.
