The invention relates to a wiper blade (10) for glass surfaces of motor vehicles. The wiper blade has a band-like, elongated, elastic wiper strip (20) which can be placed against the glass surface with a wiper lip thereof and is provided with a longitudinal groove (28, 30) on the two longitudinal sides thereof respectively. Said groove is arranged essentially in parallel in relation to the glass surface (14), at distance therefrom and in a level in such a way that a web (34) remains between the two grooves and that a spring bar (36 or 38) belonging to a band-like, elongated, spring-elastic support element (12) is accommodated in each longitudinal groove. The aim of the invention is to maintain the required flexibility of the wiper blade even when the glass surfaces are configured in a problematic manner. The distance (44) between the longitudinal edges (40, 42) of the two spring bars (36, 38) is greater than the width (46) of the web (34), whereby said edges face each other.
