The invention provides a method of manufacturing a polarizing plate, using an adhesive enabling the materials emitting fluorescence caused by being radiated by ultraviolet rays after curing to be remained. The method comprises (A) a laminating step of overlapping first and second transparent resin thin films (2,3) on the two sides of a polarizer with the help of the adhesive to obtain a laminated body (4); (B) a curing process of radiating the active energy line from the first thin film side of the laminated body (4) to cure the adhesive to thereby obtain the polarizing plate (5); (C)a fluorescence intensity measuring process of radiating ultraviolet rays from the second thin film side (3) not emitting fluorescence of the polarizing plate (5) across a polarizing filter (45) arranged in a manner of crossed nicols, measuring the fluorescence intensity come from the adhesive curing materials to determine the irradiation dose in the process (B) in a manner of obtaining the fluorescence intensity which can be judg
