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 () includes a flexible glass film () having a thickness of 150 μm or less and a resin film () laminated on the glass film with an adhesive layer () interposed therebetween. The number of contaminants having a size of 100 μm or more in the adhesive layer is preferably 10/mor less. When the contaminants protrude from the surface of the adhesive layer (), the height and inclination angle of protrusions is preferably small.
