Abstract: Embodiments of the invention provide a transparent poly(meth)acrylimide-based resin multilayer film exhibiting excellent surface smoothness, transparency, outer appearance, and resistance to puchability. According to at least one embodiment, there is provided a method for producing said transparent multilayer film, in which the transparent multilayer film in which a first poly(meth)acrylimide-based resin layer (α1), an aromatic polycarbonate-based resin layer (β), and a second poly(meth)acrylimide-based resin layer (α2) are directly laminated in said order, and in that the total light transmittance exceeds 90% and the haze is 2.0% or lower. The transparent multilayer film is produced by continuously coextruding, from a T die, a molten film of the transparent multilayer film in which the aforementioned layers were directly laminated in the aforementioned order, and by supplying and then pressing the molten film between a first mirror body that has a surface temperature between 100 and 200° C. and a second mirror body that has a surface temperature between 20 and 200° C.
