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: A method of manufacturing a member having a recessed structure, including: (1) setting a catalyst material on a portion of a first surface of a process target, wherein the first surface is made of an element that forms a fluoride having a boiling point of 550° C. or less, and the catalyst material contains an organic compound containing a polar functional group; and (2) exposing the process target to a fluorine-containing gas at 80° C. or higher, wherein through the (2), the recessed structure is formed in the first surface under the catalyst material.
