COMMUNICATION APPARATUS FOR VEHICLE

PROBLEM TO BE SOLVED: To suppress the deterioration of throughput especially in a wide-area communication line concerning a communication apparatus capable of establishing both of a narrow-area communication line and a wide-area communication line.SOLUTION: In a communication apparatus 10 for a vehicle, a narrow-area communication line establishment processing part 21 establishes a narrow-area communication line with a portable telephone 100 brought into the interior of a vehicle. A wide-area communication line establishment processing part 22 establishes a wide-area communication line with an access point 200 existing outside the vehicle. A stopping detection processing part 23 detects the stopping of the vehicle. When the stopping detection processing part 23 detects the stopping of the vehicle, a narrow-area communication line disconnection processing part 24 disconnects the narrow-area communication line established by the narrow-area communication line establishment processing part 21.
