The invention discloses a device and a method for measuring the viscosity of low-fluidity paste slurry. The measuring device comprises a funnel bracket, an adjustable platform, a slurry container, a funnel, a vacuum chamber, a vacuum pump, a vacuum meter and a supporting table. According to the measuring device, low-fluidity paste slurry can flow out from the lower opening of the funnel by utilizing vacuum negative pressure, and the relative viscosity of the paste slurry to be measured can be accurately measured by recording the time required for flowing out a certain volume of paste slurry and comparing the time with standard time, so that the measuring device can be well used for measuring and evaluating the apparent viscosity of the paste slurry at 50-175 mPa.s. The vacuum measurement environment eliminates measurement errors caused by bubbles generated by paste slurry in the measurement process, and instrument errors are reduced. The measuring device provided by the invention is simple in structure and co
