摘要： An inexpensive surface-protective film which is excellent in the ability to protect an adherend (in particular, optical sheet). With the surface-protective film (pressure-sensitive adhesive sheet) adherent to an adherend (in particular, optical sheet), an inspection of the adherend for defects can be made with satisfactory precision. Also provided is an inexpensive surface-protective film which prevents an adherend (in particular, optical member such as optical sheet) from being electrostatically charged during the processing or transportation of the adherend (in particular, optical sheet), and has the function of preventing fouling. The protective films each is a removable pressure-sensitive adhesive sheet which comprises a base layer, a pressure-sensitive adhesive layer formed on one side thereof, and an antistatic layer formed on the other side, characterized in that the antistatic layer contains a polymeric antistatic agent comprising an olefin block and a hydrophilic block.
