PROBLEM TO BE SOLVED: To provide a drawer display method displaying facility data as much as possible by drawer display without integrating dense facilities in a map. SOLUTION: In a navigation device guiding a vehicle, a map display means displays a map on a display screen on the basis of map information. A denseness determination means determines whether or not the facilities are densely distributed on the basis of facility information. When the denseness determination means determines that the facilities are densely distributed, the drawer display means displays display data about the facilities by a drawer indicating the position of the facilities on the map in the display screen. Thus, even when the facilities are densely distributed, the navigation device can display the display data about many facilities as much as possible by the drawer display without automatically integrating the facilities.
