A driving support apparatus includes an imaging member taking an image corresponding to a vehicle peripheral area; a steering angle detecting member detecting a steering-wheel steering angle; a display member disposed in a vehicle interior to display the image; and a control member predicting a driving course of the vehicle according to the detected steering-wheel angle. The control member synthesizes a predicted driving course image relating to the predicted driving course. The control member superposes the predicted driving course image at a corresponding position of the image. The control member displays on the display member the image where at least one image, on which an index is marked at least at one height position, is superposed at least on the predicted driving course image and onto a side of the predicted driving course image while the control member displays the superposed image on the display member.
