PROBLEM TO BE SOLVED: To constitute a transmission line and a flat cable which allow for suppression of unnecessary coupling between a plurality of transmission line parts, while including the plurality of transmission line parts in one multilayer insulator.SOLUTION: A transmission line includes a multilayer insulator laminating a plurality of insulator layers, and a conductor pattern arranged along the insulator layer inside of the multilayer insulator. The conductor pattern includes upper ground conductor patterns 21, 23, lower ground conductor patterns 22, 24, and a first signal conductor pattern 31 and a second signal conductor pattern 32 having a part running in parallel with each other. At a portion of the parallel running part, the upper ground conductor patterns 21, 23 and lower ground conductor patterns 22, 24 sandwich the first signal conductor pattern 31 and second signal conductor pattern 32 in the lamination direction of the insulator layer, and include a first vacancy H1 formed between the first signal conductor pattern 31 and second signal conductor pattern 32.SELECTED DRAWING: Figure 2 |
