SOLUTION: This wiper blade 10 is provided with a lip part 31, a head part 33 formed with vertebra mounting parts 33d and 33e along the longitudinal direction, a blade rubber 30 having each vertebra 40L and 40R elastically deformed along a curve of the wiping surface W of the rear window R and arranged within the vertebra mounting parts 33d and 33e of the head part 33, and a lever 20 holding the head part 33 of the blade rubber 30 and mounted on a wiper arm 11. Each of the vertebrae 40L and 40R is curved and formed along the curve of the wiping surface W. In each of the vertebrae 40L and 40R, a low rigid part 42 having low rigidity is formed from a center part 30c of the blade rubber 30 arranged in a part having a small radius of the curvature to an intermediate position 30d between the center part 30c and a distal end part 30a.
