To provide a resin laminate hardly generating appearance abnormality such as whitening or crack during molding.SOLUTION: There is provided a resin laminate having a resin layer (A) containing a resin (a) and a resin layer (B) laminated on at least one surface of the resin layer (A) and containing a resin (b) different from the resin (a), in which the resin layer (B) has pencil hardness of F or higher, the resin (a) is a polycarbonate copolymer resin. Preferably glass transition temperature (TgA) of the resin (a) is 100 to 135°C, glass transition temperature (TgB) of the resin (b) is 90 to 125°C, and the TgA and the TgB satisfy a relationship of 0≤TgA-TgB≤30.SELECTED DRAWING: None
