PROBLEM TO BE SOLVED: To prevent erroneous assembling of a first vertebra and a second vertebra on blade rubber. SOLUTION: In a wiper blade 10 constituted by holding the first vertebra 31 and the second vertebra 32 being unsymmetrical for each other in the longitudinal direction in a first holding groove 23 and a second holding groove 24 in the blade rubber 20, respectively, a first projecting part 25 is formed in the first holding groove 23, a second projecting part 26 and a third projecting part 27 are formed in the second holding groove 24, a first recessed part 33 fitted in the first projecting part 25 is formed in the first vertebra 31, and a second recessed part 34 fitted in the second projecting part 26 and a third recessed part 35 fitted in the third projecting part 27 are formed in the second vertebra 32. If the first vertebra 31 is erroneously installed in the second holding groove 24 in the blade rubber 20, a worker notices the erroneous installation because a long side of the first vertebra 31 is abutted on the second projecting part 26 and a long side on the opposite side sticks out from the second holding groove 24, thereby preventing the erroneous installation of the first and second vertebras 31, 32 on the blade rubber 20.
