摘要： A vehicle wiper blade comprises a blade support part and a lip part coupled swingably with the blade support part via a neck. The lip part comprises polyurethane. The polyurethane comprises a reactant of a composition including an isocyanate compound which includes diisocyanate and tri- or higher functional polyfunctional isocyanate, and an alcohol which includes tri- or higher functional polyfunctional alcohol. The diisocyanate has an aromatic ring in a molecule. When a molecule of the polyurethane is ionized with a mass spectrometer of a direct sample injection system, then obtained M1, M2 and M3 satisfy the following relation: M2/M1 is 0.001 to 0.028, M3/M1 is 0.020 to 0.110, and M2/M3 is 0.013 to 0.300, and a concentration of the polyfunctional alcohol in the polyurethane is 0.12 mmol/g to 0.65 mmol/g.
