An object of the present invention is to provide an antistatic pressure-sensitive adhesive having an excellent antistatic property and hardly contaminating an adherend, and a surface protective film. A pressure-sensitive adhesive comprising a copolymer (A) and an ionic compound composed of an anion represented by chemical formula (1) and a cation (B), The copolymer (A) contains 0.1 to 10% by weight of a monomer (C) containing an active hydrogen group and 1 to 40% by weight of a monomer (D) containing an alkylene oxide chain. A pressure-sensitive adhesive, which is a copolymer of monomers and has a glass transition temperature of −85 to 0 ° C., and the base material film. A surface protective film formed with an adhesive layer. [Selection figure] None |
