Zusammenfassung:PROBLEM TO BE SOLVED: To provide an on-vehicle radio apparatus and on-vehicle radio communication system capable of performing radio communication without increasing loss upon reception even in use of an existing radio LAN module with no exclusive design or a Bluetooth(R)module.SOLUTION: The on-vehicle radio apparatus includes a switch 601 that opens a coupling output of a directional coupler 108 and a termination resistance 109. The switch 601 opens the coupling output of the directional coupler 108 and the termination resistance 109 when a radio LAN module 107 receives information from an external apparatus.
