PURPOSE:To improve a wiping property and a juddering property by forming the wiping part of a wiper blade which is in contact with a glass face with a vulcanized rubber formed with a nitrile rubber-polyvinyl chloride polymer containing a 5-75 wt.% polyvinyl chloride. CONSTITUTION:A wiper blade 1 has a wiping part 3 which is brought into contact with a glass face on its lower end and is supported by a wiper body installing part 6. And, the wiping part 3 is formed with a vulcanized rubber with a rubber component of nitrile rubber and polyvinyl chloride polymer containing a 5-75 wt.% polyvinyl chloride. Thereby, both wiping property and juddering property can be improved and maintained for a long time.
