Provided is a high-productivity method for industrial manufacture of a laminate with one metal-plated side. Said method results in excellent interlayer adhesion between an insulating film and a metal foil, with no variations in adhesive strength. The provided method also inhibits the formation of aesthetic defects such as wrinkles. The provided method, which manufactures a laminate in which a metal foil (B) is bonded to an insulating film (A) that has an adhesive surface comprising a thermoplastic resin, uses a divider film (C), both sides of which have a surface roughness (Rz) of at most 2.0 µm. Insulating films (A), metal foils (B), and the divider film (C) are layered between a pair of pressure rollers (r1 and r2) in the order r1, B, A, C, A, B, r2 and bonded via thermocompression bonding. Two laminates, each with one metal-plated side, can then be separated from the divider film (C).

Also provided are a method for forming the same, an electronic device member including the formed article, and an electronic device including the electronic device member.

The present invention provides a film that is a multilayer laminated film that reflects light in a specific band and does not have interlayer delamination, which is a problem when polyethylene naphthalate resin is used. The present invention is a multilayer laminated film, which is characterized in that it is a multilayer laminated film obtained by alternately laminating at least 201 layers of A layer and B layer, and the A layer contains a main repeating unit of 2,6- Polyester A of ethylene naphthalate, the B layer contains polyester B, the main repeating unit of the polyester B is composed of ethylene terephthalate, and the polyester B has the same composition as A The refractive index of the polyester of the layer is relatively low, and the polyester A satisfies the following requirements: (1) The amount of carboxylic acid terminal groups is 5 eq / ton or more and 20 eq / ton or less. (2) The phosphoric acid alkali metal salt is contained in a range of 1.3 mol / ton to 3.0 mol / ton, and phosphoric acid is contained in a molar ratio of 0.4 to 1.5 times relative to the alkali metal phosphate. (3) The intrinsic viscosity is not less than 0.55 and not more than 0.63.
