Abstract
A wiper blade comprising a body made of an elastomeric material; and a surface coating layer positioned on a surface of the body and comprising a fluorine-containing resin having hydroxyl groups in the molecules thereof and a hardening agent having reactivity with the hydroxyl groups and optionally a solid lubricant. The surface coating layer is formed only on both side surfaces of the body. Thus, the wiper blade has a high degree of flexibility and restoring property; a high degree of durability; and judders in a slight extent when it slides on a glass surface in contact therewith; a high wiping performance; and maintains its wiping performance for a long time.
