PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive film comprising an adhesive layer having excellent antistatic properties, a supporting layer and an intermediate layer for sticking them fast. SOLUTION: The pressure-sensitive adhesive film comprises (A) the adhesive layer comprising (A-1) a hydrogenated product of a polymer composed of an aromatic vinyl compound and a conjugated diene compound and (A-2) a block copolymer having (A-2-1) a block of a polyolefin and (A-2-2) a block of a hydrophilic polymer, (B) the intermediate layer comprising a block copolymer having (B-1) a block of a hydrogenation product of a block polymer having (B-1-1) an aromatic vinyl compound-based polymer block and (B-1-2) a conjugated diene compound-based polymer block, and (B-2) an aromatic polycarbonate and/or a polyurethane block, and (C) an electrostatic supporting layer having (C-1) a styrenic resin and (C-2) a block copolymer having (C-2-1) a block of a polyamide and/or a polyester, and (C-2-2) a block of a hydrophilic polymer.
