To provide a relay device system and a relay device that can improve robustness against attacks by unauthorized communication from outside a vehicle.SOLUTION: A relay device system is mounted on a vehicle. The relay device system includes: a wireless relay device that wirelessly communicates with a communication device provided outside the vehicle; and a plurality of cable relay devices that are connected in series on a downstream side of the wireless relay device assuming that the communication device is on an upstream side with respect to the radio relay device. Each of the cable relay devices includes a communication unit that communicatively connects to an ECU for controlling an on-vehicle device mounted on the vehicle.SELECTED DRAWING: Figure 1
