Provided are a server device, a communication terminal, a route retrieval system, and a computer program that are capable of setting a currently optimum guidance route for a moving object. Specifically, when a route retrieval start condition is satisfied, a communication terminal 5 retrieves a route from a departure point to a destination based on terminal-side map information 48 provided in the communication terminal 5, and transmits, to a server device 3, a route retrieval request and route information for identifying a continuous link array corresponding to a predetermined distance from the departure point in a terminal-recommended route that is the retrieved route. When the route retrieval request is received, the server device 3 retrieves a route from the departure point to the destination that includes at least a part of the link array identified by the route information, and delivers the retrieved route to the communication terminal 5.
