1. A communication apparatus comprising:
a first conductor and a second conductor;
an analog circuit that includes a circuit element to be connected to the first conductor, and processes a differential signal represented by a voltage difference between two conductive wires;
a connection circuit that includes a circuit element different from a capacitor, and is to be connected to the analog circuit;
a communication circuit that receives, via the connection circuit, the differential signal processed by the analog circuit, and generates a signal for which a potential of the second conductor is used as a reference potential, based on the received differential signal;
a connection element that is a circuit element different from a capacitor, and is to be connected between the first conductor and the second conductor; and
a conductive housing box that houses the first conductor, the second conductor, the analog circuit, the connection circuit, the communication circuit, and the connection element,
wherein the housing box is electrically connected to a conductor whose surface area is the larger of the first conductor and the second conductor.
