Abstract
A flexible substrate includes a dielectric having flexibility, a first line, a second line, and ground electrode. The dielectric has a first surface and a second surface opposed to the first surface. The first line, the ground electrode, and the second line are laminated in this order in layers from the first surface to the second surface. When the flexible substrate is seen through from the thickness direction of the flexible substrate, the first line has a line-symmetrical portion that is line-symmetrical with respect to the second line with a virtual intermediate line (LM) serving as a symmetric line.
