<p>Provided is a flat cable which has reduced thickness, and which is capable of suppressing fluctuation of characteristic impedance. A dielectric element (12) is formed by laminating a plurality of dielectric sheets (18). A signal line (20) is provided on the dielectric element (12). A reference ground conductor (22) is provided further toward the positive direction side in the z axis direction than the signal line (20), and is provided with a plurality of openings (29) that are aligned with each other along the signal line (20). An auxiliary ground conductor (24) is provided further toward the negative direction side in the z axis direction than the signal line (20), and is provided with a plurality of openings (30) that are aligned with each other along the signal line (20). The distance between the reference ground conductor (22) and the signal line (20), said distance being in the z axis direction, is larger than the distance between the auxiliary ground conductor (24) and the signal line (20), said distance being in the z axis direction. The size of the openings (29) is smaller than the size of the openings (30).</p> |
