1. A conversion cable comprising:
a connector to be connected to an electronic device that outputs a digital voice signal;
an IC having a function of converting a digital voice signal supplied through the connector into an analog voice signal; and
an output unit for an analog voice signal output from the IC,
wherein the IC holds an encryption key for permitting the electronic device to output a digital voice signal that requires copyright protection,
a relay cable connects the IC and the output unit,
the relay cable is a coaxial structure line, and a shield wire of the coaxial structure line functions as an antenna for receiving a digital broadcast,
the connector has a configuration of a plug,
an RF signal of a digital broadcast is supplied to the plug,
a first array including a plurality of pins and a second array including a plurality of pins are provided substantially in parallel in the plug, and
both or any of a first pin and a second pin is set for supplying an RF signal, the first pin being included in the first array, the second pin being included in the second array and positioned diagonally to the first pin.
