• a cable including a power cable including a power line that supplies power and a power shield line that is formed by a braided wire and shields the power line, and a signal cable including a signal line that transmits electric signals and a signal shield line that is formed by a braided wire and shields the signal line;
• a control unit that is connected to one end of the power line and one end of the signal line, includes a control-side ground, and controls supply of the power and transmission of the electric signals, and
• a controlled unit that is connected to another end of the power line and another end of the signal line, includes a controlled-side ground, receives supply of power from the control unit, and exchanges the electric signals with the control unit,
• wherein the power shield line is connected to the control-side ground and the controlled-side ground,
• the signal shield line is connected to the control-side ground and the controlled-side ground, and
• at least one of the power cable and the signal cable includes an earth line that connects the control-side ground and the controlled-side ground to each other.
