PROBLEM TO BE SOLVED: To allow the wiper blade of a wiper arm to have an appropriate error angle. SOLUTION: The wiper blade 2 comprises blade rubber 3 and an elastic member 4 composed of a plate spring given a torsion characteristic. The torsion characteristic by which the overall length of the elastic member is curved in a spiraling direction is given to the elastic member 4 to form an attitude correcting part and the elastic member 4 is deflected in the direction to approach a natural state to thereby cause both longitudinal ends 3f and 3g of a lip part 3a to assume oppositely collapsing attitudes so as to correct the attitude of the wiper blade.
