Functional film laminate and method for producing functional film laminate

摘要

Provided is a functional film laminate capable of suppressing deformation during production. A functional film having a functional layer formed on the first surface side of the base material and a peelable protective film bonded to the second surface side of the base material, the thickness of the protective film being 20 μm or more The functional film laminate is configured to satisfy 100 μm or less, surface roughness (arithmetic average roughness; Ra) of 150 nm to 800 nm, and an elastic modulus in the thickness direction of 4.0 GPa to 6.5 GPa.
