This information management device is equipped with a travel range specifying unit which specifies the travel range which is the range of roads on which a vehicle may travel if having deviated from a preset planned route. The travel range specifying unit calculates the travel range on the basis of the time required to recalculate the planned route, and the speed of the vehicle.
