Abstract:
1. A signal transmission line comprising: a line portion including stacked insulating sheets made of a flexible material such that the line portion can be bent; a signal line extending within the line portion; a first conductive layer provided within the line portion on one side in a lamination direction with respect to the signal line and having a line width equal to or smaller than a line width of the signal line; and a second conductive layer provided within the line portion on another side in the lamination direction with respect to the signal line and having a line width larger than a line width of the signal line; wherein the signal line overlaps the first conductive layer and the second conductive layer when seen in a planar view from the lamination direction; the signal line is provided between the first conductive layer and the second conductive layer without any other conductive layer; and the second conductive layer includes a first end and a second end opposite to the first end, the first end being electrically connected a first ground conductor and the second end being electrically connected to a second ground conductor.
