The topic of the present invention is to provide a thin laminate with excellent adhesion between the layer components. The solution is as follows: the laminated body according to the embodiment of the present invention has: a polarizing plate containing a polarizer, a functional layer, a resin layer, and an adhesive layer; the resin layer and the adhesive layer are arranged adjacent to each other; and the resin layer contains resin with glass transition temperature above 85 DEG C and weight average molecular weight Mw is above 50,000 but less than 500,000, and isocyanate compounds; the aforementioned isocyanate compounds include at least one compound is selected from toluene diisocyanate, diphenylmethane diisocyanate, stubble diisocyanate, and other derivatives the like. The content of the aforementioned resin in the aforementioned resin layer is more than 50% by weight and less than 90% by weight, and the content of the aforementioned isocyanate compounds in the aforementioned resin layer is more than 10% by
