Abstract: A method of manufacturing a glass resin laminated body includes a step of sticking a glass film on a resin film via an adhesive layer while holding the glass film and the resin film between a first roller that presses against the resin film and a second roller that is disposed opposite to the first roller and that presses against the glass film. A ratio of an elastic modulus P1 of a surface layer of the first roller to an elastic modulus P2 of the resin film P1/P2 satisfies a relation of 3×10−3≤P1/P2≤1.0.

Abstract: Provided is an optical laminate in which optical defects is less likely to occur when used in an optical device such as a display. A laminate (101) includes a flexible glass film (10) having a thickness of 150 μm or less and a resin film (20) laminated on the glass film with an adhesive layer (50) interposed therebetween. The number of contaminants having a size of 100 μm or more in the adhesive layer is preferably 10/m2 or less. When the contaminants protrude from the surface of the adhesive layer (50), the height and inclination angle of protrusions is preferably small.
