PROBLEM TO BE SOLVED: To discover a guide route for reaching a destination via one or a plurality of passing spots desired by a user, while visiting the passing spots desired by the user at proper timing. SOLUTION: A route pattern generation part 13 searches for a plurality of route patterns having the mutually different visiting order of the passing spots, which are the plurality of route patterns for reaching the destination via the passing spots designated by a passing-spot selection part 12. An eligible route determination part 17 determines whether a passing spot in a route pattern discovered by the route pattern generation part 13 satisfies passing spot conditions set beforehand or not. In addition, a route pattern edition part 18 executes correction of the guide route relative to the route pattern, and thereafter allows the eligible route determination part 17 to determine whether the passing spot in the corrected route pattern satisfies the passing spot conditions.
