PROBLEM TO BE SOLVED: To draw a route defined by two-dimensional coordinates to be satisfactorily laid on a road face of a road expressed three-dimensionally. SOLUTION: A navigation apparatus includes a means for storing a link data and a three-dimensional data of the road, a means for setting a plurality of points P1 to Pn between the start point and end point of a link constituting the route, in every of the links constituting the route, a means for finding corresponding points Pm1 to Pmn on the road face 82 of the road expressed by the three-dimensional data, in every of the plurality of sample points P1 to Pn, and a display means for displaying the route on the road face of the road expressed three-dimensionally, by connecting the found points Pm1 to Pmn.
