PROBLEM TO BE SOLVED: To provide a wiper blade capable of appropriately wiping even a glass face with high curvature. SOLUTION: At both ends of a primary lever 13, first stage secondary levers 15A, 15A are supported by rotating shafts 14, and in end side edge parts of the first stage secondary levers 15A, 15A, second stage secondary levers 15B, 15B are supported by rotating shafts 16. In a center side edge part of each of the first stage secondary lever 15A, 15A, one yoke lever 18 is supported by a rotating shaft 17, and in an end side edge part of each of the second stage secondary levers 15B, 15B, one yoke lever 18 is supported by a rotating shaft 19. Ten holding claws 10 are provided in the center side edge parts of the second stage secondary levers 15B, 15B and both end parts of the four yoke levers 18, and blade rubber is held by the holding claws 10. Relationship between a clearance X1 between the first rotating shaft 14 and the third rotating shaft 17, a clearance X2 between the first rotating shaft 14 and the second rotating shaft 16 and a clearance X3 between the second rotating shaft 16 and the fourth rotating shaft 19 is set to be X1>X2>X3, and clearances Y between the holding claws 20, 20 are set equal to each other.
