A route search apparatus comprises a road information storage part configured to store road information including link information comprised of single link information and composite link information; and a route searcher configured to search a recommended route between two different points using the link information. The single link information includes information regarding an approach link that is a link approaching to a node at one end of a target link, an exit link that is a link exiting from a node at the other end of the target link, and a cost of the target link for entering from the approach link and exiting to the exit link. The composite link information includes information regarding an approach link that is a link approaching to a node at one end of a target link array, an exit link that is a link exiting from a node at the other end of the target link array, and a cost of the target link array for entering from the approach link and exiting to the exit link.
