PROBLEM TO BE SOLVED: To provide an anti-static film which is suitable for the partitioning of a clean room, a wall and a curtain, and a cover for instruments or the like in the clean room, and is excellent in surface peculiar resistance and strength. SOLUTION: This anti-static film is a laminated film constituted of two or more layers having at least a layer (A) and a layer (B). The layer (A) consists of a resin composition containing a polymer type anti-static agent having 10 to 40 wt.% of a polypropylene based resin, and 90 to 60 wt.% of a polyether-polyolefin block copolymer as the constituting components. The layer (B) consists of a resin composition containing a polymer type anti-static agent having 80 to 100 wt.% of a polypropylene based resin, and 20 to 0 wt.% of a polyether-polyolefin block copolymer as the constituting components.
