An acrylic resin film that includes 50-99 parts by mass of a methacrylic resin (A) that has 80 wt% or more of a methyl methacrylate unit, and includes 1-50 parts by mass of a block copolymer (B) that has 40-90 wt% of methacrylic acid ester polymer blocks (b1) and 10-60 wt% of acrylic acid ester polymer blocks (b2) (provided that the methacrylic resin (A) and the block copolymer (B) total 100 parts by mass). The weight-average molecular weight (Mw(A)) of the methacrylic resin (A), the maximum weight-average molecular weight (Mw(b1)) of the methacrylic acid ester polymer blocks (b1), and the maximum weight-average molecular weight (Mw(b2)) of the acrylic acid ester polymer blocks (b2) satisfy (1) and (2). (1) 0.5≤Mw(A)/Mw(b1)≤2.3. (2) 30000≤Mw(b2)≤120000. |
