An alarm system includes a miniature camera ( 10 ), a loudspeaker ( 20 ), a vehicle speed sensor ( 30 ), a longitudinal G sensor ( 40 ), a lateral G sensor ( 50 ) and an on-vehicle unit ( 60 ). A CPU ( 60 a) of the on-vehicle unit ( 60 ) executes respective programs ( 61 )-( 64 ) in a ROM ( 60 h), thereby outputting, if a traveling distance during a period for which a driver D continues to take an abnormal behavior exceeds a predetermined value when a traveling state of an automobile is kept stable, an alarm corresponding to a magnitude of the excess over the predetermined value from the loudspeaker ( 20 ). The alarm system is thus configured and is therefore capable of exactly outputting the alarm when a danger actually rises.
