PROBLEM TO BE SOLVED: To provide a wiper having bendability required for sliding a sliding portion along a cleaned surface, and maintaining a reduced friction coefficient even if the surface of the sliding portion is worn. SOLUTION: The wiper 1 includes a main body portion 2 not making contact with the cleaned surface 10, and the sliding portion 3 integrated with the main body portion 2 and making contact with the cleaned surface 10. A friction reducing material for reducing friction resistance between the sliding portion and the cleaned surface, is blended with the sliding portion, but not blended with the main body not making contact with the cleaned surface.
