A wiper blade for wiping windows of motor vehicles has an elongated rubber-elastic wiper strip placeable on a window to be wiped and arranged substantially longitudinally axially parallel on a surface of a strip-shaped, spring-elastic support element which is connected with a wiper arm which is spring loaded toward the window and driven transversely to a longitudinal extension of the wiper blade, and a leading-edge face extending longitudinally of the wiper blade and substantially parallel to the window and facing into a wind so as to form an acute angle with the window.
