The invention relates to an adhesive sheet and an optical member. The adhesive sheet (surface protective film) has a topcoat layer rarely whitened and provides excellent re-removability and operating performance, and an appropriate adhesive force for preventing gradual upwarping or peeling is provided. The adhesive sheet comprises an adhesive layer formed by adhesive composition on a single surface of a supporting film, and a top coat layer is arranged on the other surface opposite to the surface having the adhesive layer of the supporting film. The adhesive sheet is characterized in that the top coat layer contains wax as a lubricant and a polyester resin as a binder, on the surface of the top coat layer, the back adhesive force (A) of a registered trademark after adhesion of 30 minutes at the temperature of 23 DEG C with a peeling speed of 0.3m/min is above 4.0 N/24mm, the adhesion of an adhesion surface of the adhesive layer pasted on a TAC surface for 30 minutes at the temperature of 23 DEG C with a peeling speed of 0.3m/min for a polarizing plate is below 0.1 N/25mm, and the offset of the adhesive layer whose adhesion area 200 mm<2> is attached to the TAC polarizing plate and implementing a creep test with a load of 500 g for 30 minutes at the temperature of 23 DEG C is below 2.5 mm.
