Abstract: To provide a glass resin laminate of the present invention, in which the glass substrate and the resin layer containing a TFE polymer are strongly laminated, is hardly warped and is excellent in the electrical properties, a composite laminate further having a metal foil, and methods for producing them.
A glass resin laminate comprising a glass substrate 10 having an uneven surface 12 with an arithmetic mean roughness of at least 5 nm, and a resin layer containing a tetrafluoroethylene polymer in contact with the uneven surface 12,



wherein the uneven surface 12 has specific convex portions 21 and 22 which narrow at at least a part of the root portion as compared with the tip portion.
