PROBLEM TO BE SOLVED: To provide a wiper blade free from wiping irregularity even if a glass face to be wiped has a large curvature and different curving degree in a longitudinal direction of the rubber by changing the contact angle of a wiping-surface pressure contact part of the blade rubber to the glass face to be wiped from the central part of the blade rubber to both end parts in the longitudinal direction, by gradually changing the shape of the rubber, or by gradually changing the angle against the glass face to be wiped at a plurality of blade rubber grip parts gripping the rubber. SOLUTION: The wiper blade has a long blade rubber having a wiping-surface pressure contact part pressed on a glass face to be wiped at tip end, blade rubber grip parts gripping the rubber and a plurality of lever yokes arranged in a longitudinal direction of the rubber. The wiping-surface pressure contact part from the central part of the rubber to both end parts of in the longitudinal direction was formed so that the degree of contact angle against the glass face to be wiped to be gradually inclined up to a required angle in a counter direction.
