Abstract
A method for producing a pressure-sensitive adhesive sheet according to the present invention includes: forming a pressure-sensitive adhesive layer 10 formed of a transparent base pressure-sensitive adhesive material on a support S; curing the pressure-sensitive adhesive layer 10; providing a solution 12 of an additive 11; applying the solution 12 to one of opposite surfaces of the cured pressure-sensitive adhesive layer 10a to cause the additive contained in the solution 12 to infiltrate from the one surface in a thickness direction of the pressure-sensitive adhesive layer 10a; and drying the pressure-sensitive adhesive layer 10a.
