This method for producing an acrylic resin film produces an acrylic resin film that contains an acrylic resin and rubber particles, and comprises: a step for preparing a dope that contains an acrylic resin which has a glass transition temperature (Tg) within the range of from 120°C to 180°C and a weight average molecular weight of from 300,000 to 4,000,000 and rubber particles which have a core-shell structure; a step for preparing a dope by filtering the above-described dope with use of a filter that has a filtration accuracy within the range of from 5 μm to 100 μm; a step for casting the dope after filtration onto a supporting body and separating a web therefrom; and a step for drying the web. This method for producing an acrylic resin film is also configured such that if parallel light rays are incident on the acrylic resin film at an angle of 75 degrees and a measurement is performed with an optical comb width of 0.125 mm, the C value of transmitted images is within the range of from 80% to 100%.
