1. A method for connecting a differential transmission cable, comprising:
- connecting a pair of conductors for transmitting a differential signal to a first contact point; and
connecting a second shield, provided on a periphery of a first shield via an insulating layer, to a second contact point in a state that the first shield provided on a periphery of the pair of conductors via a dielectric layer is not electrically connected to anywhere.
