Stage: PROBLEM TO BE SOLVED: To suppress that it is erroneously determined to visually observe an in-vehicle device, despite the fact that a front target outside a vehicle is visually observed.SOLUTION: An inattentive state determining device 4 detects a target present in front of a vehicle, based on peripheral data indicating a situation around the vehicle; detects a viewpoint position and a visual line direction of a driver, based on driver data indicating a state of the driver; changes a visual observation determination range in a vertical direction in order to determine whether or not the driver visually observes an in-vehicle device arranged in front of a cabin thereof, according to a positional relation to the target; determines that the in-vehicle device is inattentively observed if the visual line direction of the driver is continuously kept within the visual observation determination range for a predetermined inattentive state determination time or more; and changes the visual observation determination range in such a manner that an upper end position in the visual observation determination range is made to be at a lower side by comparing when the target is located at a nearby place with when the target is located at a distance.SELECTED DRAWING: Figure 3 (Grant)
