To provide a composite resin sheet wherein a metal vapor deposition film is constituted so that a metal vapor deposition layer is formed on a biaxially stretched PET, and a biaxially stretched PET is further laminated on the metal vapor deposition layer, and as the resin part serving as a base material of the metal vapor deposition layer is difficult to expand, crack hardly occurs in the metal vapor deposition layer of the metal vapor deposition film at the time of solid molding, with superior designability, a molding method of the composite resin sheet, and a decorative member formed by using the composite resin.

The composite resin sheet 1 is formed by laminating the metal vapor deposition film 10 on a transparent resin sheet 22 via an adhesive layer 20. The metal vapor deposition film is formed by providing a metal vapor deposition layer 14 on the biaxially stretched PET 12a and further laminating a biaxially stretched PET 12b on the metal vapor deposition layer 14.
