<p>Provided is an adhesive sheet which has excellent antistatic properties and excellent image sharpness balance and which is suitable for surface protective films and the like. An adhesive sheet of the present invention comprises a back surface layer (A), a base layer (B) and an adhesive layer (C), and the back surface layer (A) and the adhesive layer (C) serve as the outermost layers. The back surface layer (A) has a surface resistivity of less than 1 × 1014 ?/?. When the image sharpness of the back surface layer (A) in the MD direction with a slit width of 0.25 mm is represented by X (%) and the image sharpness of the back surface layer (A) in the TD direction with a slit width of 0.25 mm is represented by Y (%), the relation of 0.6X = Y = 1.4X is satisfied.</p>
