To provide a terminal circuit unit for on-vehicle multiplex communication capable of reducing the number of waste vacant connector fitting part for miniaturization by easily corresponding to a change of the number of connection.
A required number of hub-type joint connector 20, to which a terminal communication device is connected, can be connected to a joint connector 20 housing a terminal resistant circuit 40 by short pins 50 in response to a change of the number of connection. Consequently, even if the number of circuit to be connected is changed, connection can be facilitated by changing the number of the joint connector 20 to be connected. With this structure wherein the joint connectors 20 are directly connected to each other, miniaturization is enabled. The short pin 50 electrically connects a terminal resistant housing part 23 of one joint connector 20 to a vacant cavity 21a of other joint connector 20.
