Zusammenfassung:	A cleaning wiper blade comprises a hand grip part and an elastic part. The elastic part comprises a polyurethane. The polyurethane comprises a reactant of a composition including an isocyanate compound which includes diisocyanate and polyfunctional isocyanate, and an alcohol which includes 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 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.
