PROBLEM TO BE SOLVED: To provide wiper blade rubber having excellent low friction property and wiping-out performance.SOLUTION: Wiper blade rubber comprises a lip section wiping a wiping-out surface. The lip section includes a rubber section (A) and a fluororesin layer (B) provided on the rubber section (A). The fluororesin layer (B) is provided on a surface of the lip section and the rubber section (A) is formed of a rubber composition for vulcanization. The fluororesin layer (B) is formed of a fluorine polymer composition and has a thickness of 50 μm or less. The fluorine polymer composition contains a fluorine polymer (b1) having a copolymerization unit derived from chlorotrifluoroethylene. The rubber section (A) is vulcanized and adhered to the fluororesin layer (B). |
