1. A high-speed transmission device, comprising:
a substrate;
a control device provided on the substrate;
a first connector disposed at a position near the control device on the substrate and electrically connected to the control device via the substrate;
a second connector disposed at a position away from the control device on the substrate and equipped with an apparatus for transmitting/receiving a signal to and from the control device; and
a cable assembly disposed between the first connector and the second connector,
wherein
the cable assembly comprises:
a cable row in which a plurality of cables each transmitting a differential signal are arranged side by side, the cables each comprising an internal conductor and an external conductor;
a paddle card substrate provided with first electrodes for signal and first electrodes for ground, front end portions of the internal conductors of the plurality of cables being electrically connected to the first electrodes for signal, and front end portions of the external conductors of the plurality of cables being electrically connected to the first electrodes for ground; and
a first conductive resin cover covering the paddle card substrate, exposed internal conductors of the cables, and connection portions of the external conductors of the cables,
wherein the first conductive resin cover is not electrically connected to the first electrodes for signal, but is electrically connected to the first electrodes for ground.
