PROBLEM TO BE SOLVED: To provide a plate-like molded article made of a methacrylic resin composition, which has excellent mechanical properties, surface smoothness, transparency, and the like, and has little change in haze in a wide temperature range.SOLUTION: The plate-like molded article is made of a methacrylic resin composition comprising: 10 to 99 pts.mass of a methacrylic resin (A) containing 80 mass% or more of a methyl methacrylate unit; and 90 to 1 pts.mass of a block copolymer (B) containing 10 to 80 mass% of a methacrylate polymer block (b1) and 90 to 20 mass% of an acrylate polymer block (b2). A weight average molecular weight Mwof the methacrylic resin (A), a maximum weight average molecular weight Mwof the methacrylate ester block (b1), and a maximum weight average molecular weight Mwof the acrylate polymer block (b2) satisfy the following (1) and (2): 0.5≤Mw/Mw≤2.5 (1) and 40000≤Mw≤120000 (2). |
