1. A flexible substrate comprising:
a base substrate that has flexibility;
a connecting portion on the base substrate and connectible to a mounted circuit; and
a first line and a second line at the base substrate and connected to the connecting portion; wherein
the first line and the second line include:
a first region in which the first line and the second line extend in parallel or substantially in parallel with each other; and
a second region in which the first line and the second line are closer to each other than in the first region and coupled to each other; and
a length of each of the first line and the second line in the second region is equal or substantially equal to one quarter of a wavelength of a signal that propagates through the first line and the second line.
