Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a viscosity-measuring device by which the viscosity of a solution to be measured can be measured with satisfactory accuracy over a wide viscosity range, by improving a funnel viscosimeter. SOLUTION: The viscosity measurement device is composed of a conical container-shaped liquid inlet part 1a and a cylindrical measurement part 2a which is hung vertically from its lower end, the upper part of the measuring part 2a is constituted in a cylindrical buffer zone 3a which has a length of 15 mm and a diameter of 8 mm, and the lower part is constituted into a cylindrical measurement zone which has a length of 20 mm and a diameter of 2.5 mm. Five hundred ml of the solution to be measured is put into the part 1a, its passing time from the lower end of the zone 4a is measured, and the viscosity is measured.
