Abstract
A methacrylic resin composition containing 10 to 99 parts by mass of a methacrylic resin (A) containing 80% by mass or more of a methyl methacrylate unit, and 90 to 1 part by mass of a block copolymer (B) containing 10 to 60% by mass of a methacrylic acid ester polymer block (b1) and 90 to 40% by mass of an acrylic acid ester polymer block (b2), where the total of the methacrylic resin (A) and the block copolymer (B) is 100 parts by mass, where a weight-average molecular weight Mwof the methacrylic resin (A), a maximum weight-average molecular weight Mwof the methacrylic acid ester polymer block (b1) and a maximum weight-average molecular weight Mwof the acrylic acid ester polymer block (b2) satisfy (1): 0.5≦Mw/Mw≦2.5 and (2): 40000≦Mw≦120000.
