To provide an object detector which reduces erroneous detection of an object at night or darkness equivalent to the night.
When it is not a night state (S400:No), the object detector sets a determination threshold to 50% (S402). When it is a night state (S400:Yes), the object detector instructs, when the object in front of a vehicle is detected except a preceding vehicle and an oncoming vehicle (S404:Yes), to make a headlight into a high beam (S406) and sets the determination threshold to 65% (S408). When the object is not detected (S404:No), the object detector sets, when the headlight is the high beam (S410:No), the determination threshold to 65% (S408), and sets, when the headlight is a low beam (S410:Yes), the determination threshold to 80% (S412). The object detector instructs, when detection reliability including a camera and a radar is the determination threshold or more (S414:Yes), at least one of an alarm and automatic braking (S416).
