PROBLEM TO BE SOLVED: To provide an acrylic film unlikely to cause poor appearance on winding even when surface treatment or printing is applied thereon. SOLUTION: An acrylic film comprising a methacrylic resin and acrylic rubber particles is subjected to knurling processing at a side edge thereof. The knurling has a height of 3-30μm, and the part which is not subjected to knurling processing has a thickness of 50-500μm. The methacrylic resin preferably includes a polymer obtained by polymerizing an alkyl methacrylate in an amount of 50-100 wt.%, an alkyl acrylate in an amount of 0-50 wt.%, and another monomer in an amount of 0-49 wt.%. The acrylic rubber particles preferably include particles comprising an elastic polymer obtained by polymerizing an alkyl acrylate in an amount of 50-99.9 wt.%, another monofunctional monomer in an amount of 0-49.9 wt.%, and a polyfunctional monomer in an amount of 0.1-10 wt.%.
