PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive sheet capable of achieving improvement in antistatic properties and pickup properties, and an optical member protected by the pressure-sensitive adhesive sheet.SOLUTION: The pressure-sensitive adhesive sheet includes a first resin layer, an adhesive layer, a second resin layer, and a pressure-sensitive adhesive layer formed of a pressure-sensitive adhesive composition in this order. The ratio of the thickness of the adhesive layer to the sum of the thickness of the first resin layer and the thickness of the second resin layer is 0.50 or less. The storage modulus at 23°C of the adhesive layer is 1.0×10Pa or more and less than 5.0×10Pa. The pressure-sensitive adhesive sheet also includes a top coat layer on a surface of the first resin layer which is opposite to the surface having the pressure-sensitive adhesive layer. The top coat layer is formed of a composition for the top coat layer which contains a polyaniline sulfonic acid as a conductive polymer component, a polyester resin as a binder component, and an isocyanate compound as a crosslinking agent. The pressure-sensitive adhesive layer contains an organopolysiloxane having an oxyalkylene chain.SELECTED DRAWING: None |
