To provide a wiper blade provided with a fin structure suppressing height, reducing concentration of excessive pressing force to a central part by distributing the pressing force in a longitudinal direction of a blade rubber, ensuring good wiping property by allowing elastic following relative to a wiping surface of the blade rubber by backing at both ends and further sufficiently preventing floating up from the wiping surface during traveling of the vehicle.

The wiper blade 1 is provided with the blade rubber 4; the backing 5 having the central part projectedly curved to an opposite wiping surface 20a side and attached along a longitudinal direction of the blade rubber; and a lever 3 provided on a distal end of an arm part 11 extending to both sides in a longitudinal direction from a holder part 10 connected with a wiper arm 2 and retaining the blade rubber or the backing by a retaining part 12 arranged at an intermediate part of the end in the longitudinal direction of the blade rubber and the holder part 10. Fin parts 13, 4d are formed on the arm part 11 of the lever 3 and the blade rubber 4 such that the shape is continued.
