PROBLEM TO BE SOLVED: To provide a route guiding system capable of guiding proper route in voice corresponding to various states of intersections. SOLUTION: At each intersection on the guiding route, a voice guide indicating progress to the left or the right is provided, when (1) the relative angles of extended line of the ingress road and all roads connecting to the intersection are within -35°to -15°or +15°to +35°, and (2) the relative angle of the ingress road and a leaving road to leave from the intersection is larger than the relative angle of the ingress road and the other roads. Otherwise, the voice guide progressing to a direction within the angle range in which the relative angle of the ingress road and the leaving road belongs, is performed.
