1. A transmission line component comprising:
a substrate with a shape extending in a first direction, and including an insulating material;
a first signal conductor and a second signal conductor on or in the substrate; and
a common-mode choke coil including a coupling between the first signal conductor and the second signal conductor; wherein
the substrate includes:
a coil portion in which the common-mode choke coil is provided; and
a signal line portion in which the coupling between the first signal conductor and the second signal conductor is weaker than the common-mode choke coil.
