To provide wiper blade rubber having excellent vibration absorptivity and shape maintainability, without substantially generating noise and vibration in wiper operation; and to provide the wiper blade rubber without substantially generating the noise and the vibration in the wiper operation, particularly to a water repellent processing-applied glass surface.

The wiper blade rubber is characterized by including acrylic rubber, a reinforcing agent and a filler, and desirably, the wiper blade rubber is 10% or less in resiliency in an impact resilience test.
