Provided is a laminate of a support (1) and a highly optically transparent polyimide film (6) serving as a base material on which a variety of devices are laminated, wherein the laminate does not delaminate even during a high-temperature process in the manufacture of a device but does allow for the polyimide film to be readily peeled from the support after a device has been manufactured on the polyimide film. A method for producing a laminate comprises: using a polyimide film (6) obtained by reacting together diamines and tetracarboxylic acids principally made of alicyclic tetracarboxylic acids, the polyimide film (6) having a mean light transmittance, glass transition temperature, and thickness within specific ranges; using a coupling agent on at least one of the surfaces where the support (1) and the polyimide film (6) face each other; implementing a patterning treatment for forming a favorably adhered portion and a readily delaminated portion of different peel strengths; and thereafter placing the support (1) and the polyimide film (6) on top of each other and applying heat and pressure. |
