Claims9
A glass cloth comprising glass having a composition that is at least 50 wt % SiO2, wherein one of a warp and a weft that constitute the glass cloth has a filament diameter of less than 3.0 μm, and the glass cloth has a thickness of 15 μm or less and a weight of 10 g/m2 or less.
A method of adjusting the filament diameter of a glass cloth, comprising the step of etching away at least 0.1 μm of the filament diameter of the glass cloth by treating the glass cloth with one or more etching solution selected from the group consisting of hydrofluoric acid, aqueous ammonium fluoride, aqueous sodium hydroxide, aqueous potassium hydroxide, aqueous sodium carbonate, ammonia water and alkaline electrolyzed water.
