PROBLEM TO BE SOLVED: To prevent error assembly and realize commonalization with respect to a communication relay device and a relay connector unit for controlling a plurality of electronic equipment by one electronic control device. SOLUTION: The communication relay device 20 is provided with a first connection means 21 to which a first wire harness connected to an electronic control device is connected, a second connection means 22 to which a second wire harness connected to the plurality of electronic equipment is connected, a communication address setting means 23 to establish a communication address with the electronic control device by a conductive pattern based on presence/absence of conduction at the plurality of connection parts, and a communication relay means 24 which is connected electrically to the first connection means 21 and the second connection means 22 and relays communications between the electronic control device and the plurality of electronic equipment based on the communication address established by the communication address setting means 23. The communication address setting means 23 is formed so as to be visible from outside the presence/absence of conduction of the plurality of connection parts and be capable of establishing or changing the conduction pattern.
