A wiper blade is proposed which is used for cleaning windshields of motor vehicles. The wiper blade has an elastic, elongated support element for an elongated wiper strip, made of flexible material, placed against the windshield to be wiped, which has on its longitudinal sides longitudinal grooves facing each other, in which runners, which are arranged at a distance from each other, of the support element are positioned, whose center section has a connecting device for a powered wiper arm, and wherein the cross section of the two longitudinal runners diminishes from their center area toward the end of the runners, wherein the two adjoining ends of the longitudinal runners are each connected in a single piece by means of a cross brace. A particularly process-oriented and assembly-friendly wiper blade results, if the longitudinal runners of the support element have an even thickness over their entire longitudinal extension and the width of the support element from its center area is reduced toward its two ends.
