A wire harness capable of forming a short circuit by use of a plurality of electric wires and a joint connector while being slenderized and reduced in weight. The wire harness includes a plurality of circuit modules each forming a short circuit. Each of the circuit modules, includes a plurality of electric wires, and a plurality of external-connection connectors, connected to respective first ends of the electric wires, and a joint connector, connected to respective second ends of the electric wires to short-circuit the electric wires. The electric wires constituting the circuit modules are bundled together so that the joint connector of each of the circuit modules is discretely disposed so as to be located in a vicinity of at least one of the external-connection connectors included in the circuit module, around which electric wires a binding tape is wound.

In a converter, the source of a first FET and the drain of a second FET are connected to one end of an inductor while the source of a third FET and the drain of a fourth FET are connected to the other end of the inductor. The sources of the first FET and the second FET are connected to each other. The cathode and the anode of a diode are connected respectively to the drain and the source of the third FET. Then, the first FET, the second FET, the third FET and the fourth FET are turned ON/OFF individually so that a voltage applied by a battery is converted. When voltage conversion is to be terminated, OFF-state of the third FET is maintained. Then, during the time that the OFF-state of the third FET is maintained, an electric current is reduced that flows from the drain of the third FET through a storage battery to the source of the fourth FET.

An in-vehicle communication system and an in-vehicle relay apparatus that can perform relaying between multiple in-vehicle networks if a new in-vehicle device is connected to a said in-vehicle network, and that can prevent, if an improper in-vehicle device is connected to the in-vehicle network, the entire system from being adversely affected by the improper in-vehicle device. The in-vehicle relay apparatus that relays information between the multiple in-vehicle networks has stored therein relay destination determination information necessary to determine a relay destination of information. If a new in-vehicle device is connected to any one of the in-vehicle networks, an acquiring unit communicates with a communication device to obtain updated relay destination determination information, a determination unit determines if the updated relay destination determination information is legitimate, and an updating unit updates the relay destination determination information of the in-vehicle relay apparatus.
