PROBLEM TO BE SOLVED: To provide an acrylic resin laminate that has a metal and/or metal oxide layer on one surface of an acrylic resin molding, shows excellence in surface hardness, surface smoothness, mirror glossiness and handleability, and has metallic glossiness. SOLUTION: The laminate has the metal and/or metal oxide layer on at least one surface of the acrylic resin molding that contains a methacrylate-based resin [A] having weight average molecular weight of 40,000 or more and a polyvinylacetal resin [B] made by (co)acetalizing a polyvinylalcohol resin having number average molecular weight of 200 to 4,000 at an acetalization degree of 55 to 83 mol% , the mass ratio [A]/[B] being 99/1 to 51/49, and that has a glass transition temperature Tg<SB>AP</SB>resulting from the methacrylate-based resin [A] between a glass transition temperature Tg<SB>A</SB>of the methacrylate-based resin [A] itself and a glass transition temperature Tg<SB>B</SB>of the polyvinylacetal resin [B] itself.
