The invention relates to a wiper blade for cleaning panes, especially for cleaning the panes of a motor vehicle. The inventive wiper blade ( 10 ) comprises an elongated, rubber-elastic wiper strip ( 14 ) that is placed against the pane ( 22 ) and that is mounted on an elongated elastic support element ( 12 ) so that its longitudinal axis is parallel thereto, a device ( 16 ) for connecting the wiper blade to a driven wiper arm ( 18 ) being directly linked with said support element. The support element ( 12 ) comprises two strip-like spring bars ( 28, 30 ) that are disposed in a plane in front of the pane and substantially parallel thereto. The lower strip surfaces ( 13 ) of the spring bars face the pane, and the adjacent inner longitudinal edges ( 48 ) thereof, at a distance ( 34 ) to one another, dip into a longitudinal groove ( 54, 56 or 106 ) that is associated with every longitudinal edge and that is open towards the longitudinal face of the wiper strip ( 14 ). The lower strip surfaces are interlinked by at least two transverse connectors ( 36, 38 ) that are arranged in the longitudinal direction at a distance to each other. The wiper blade can be produced in a more economical way if every transverse connector ( 36, 38 ) has a center section ( 42 ) that extends at a distance ( 44 ) t o the upper strip surfaces ( 11 ) of the spring bars ( 28, 30 ), thereby forming bridging connectors, the distance ( 34 ) between the two longitudinal bars ( 28, 30 ) being smaller than the bridge width ( 46 ).
