The object of the invention is a wiper blade (10) with a wiper strip (12), in the lateral longitudinal grooves (20) of which spring rails (24) are inserted as springy supporting elements. The ends of the spring rails (24) are connected with one another by a bridge (32, 54, 62, 76) in that side parts (36, 66, 80) of the bridge (32, 54, 62, 76) are supported at the upper side of the spring rail (24) and engage recesses (28, 30) of the spring rails (24), whereas a middle part (34, 64, 78) of the bridge (32, 54, 62, 76) bridges a back strip (22) of the wiper strip (12), which forms the upper boundary of the longitudinal grooves (20). It is proposed that the spring rails (24), at their front faces, have short slots (28), which extend in the longitudinal direction of the spring rails (24) and which are engaged by the I-shaped angle pieces (38, 56) of the bridge (52, 54). Lower legs (40, 58) of the angle pieces (38, 56) are directed towards the middle of the spring rails (24), gripping these from below.
