The invention provides an adhesive, which can be applied in thick film, can form an adhesive layer that is high in transparency, low turbidity, and good visibility of the adherend even in thick film application, and can form an adhesive layer having high temperature even at high temperature. Adhesive layer that can maintain high transparency, low turbidity, and heat and humidity resistance even when used in high humidity environments. The adhesive of the present invention comprises: a polyurethane polyol (A), which is a plurality of polyols (x) including a difunctional polyol (x1) and a trifunctional or higher polyol (x2), and a polyisocyanate (Y) a reaction product; a polyfunctional isocyanate compound (B); and a cellulose ester (C). |
