Provided is a vehicle-mounted relay device that can suppress failures in reading/writing of data due to electric power shortage. The vehicle-mounted relay device determines whether or not reading/writing of data is possible based on the required amount of stored power in the electric power storage device and the remaining amount of stored power in the electric power storage device needed to read/write the data. If the remaining amount of stored power is equal to or greater than the required amount of stored power, there is no risk that the remaining amount of stored power in the electric power storage device may run short before the reading/writing of the data ends. Accordingly, if it is determined that reading/writing of the data is possible, the vehicle-mounted relay device causes an ECU, which is a vehicle-mounted control device, to start reading/writing the data.
