Abstract: A glass substrate comprising a rectangular glass sheet having a first main surface and a second main surface opposite the first main surface, the glass substrate having a first side and a second side which are adjacent to each other in a view along a thickness direction of the glass sheet, in which a thickness tolerance is less than 6.26 μm in a first cross section which is a cross section in the thickness direction of the glass sheet along a straight line parallel to the first side, the thickness tolerance being a difference between the maximum value and the minimum value of the thickness of the glass sheet.

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.
