PROBLEM TO BE SOLVED: To provide a viscosity measuring method in which the viscosity as a criterion for the concentration of the effective solid content of a starch-based adhesive can be measured precisely and simply at a construction site without depending on the skill degree of operator. SOLUTION: In this method, the viscosity of a starch-based adhesive 1 which is used to paste a sheet of wallpaper or a wall cloth on a wall surface or a ceiling face is measured, The starch-based adhesive 1 is portioned into an arrangement and installation container, the portioned starch-based adhesive 1 in a prescribed amount is arranged and installed in a prescribed position on a face to be tested, and a distance at which the starch-based adhesive 1 flows and falls from the prescribed position within a prescribed time is measured.
