Abstract
A glass fiber base material for print wiring substrate is disclosed, comprising a fluorescent whitening agent attached to the surface of a sheet made of glass fibers such as woven fabrics, non-woven fabrics and paper. The glass fiber base material has excellent ultraviolet light-shielding properties and, hence, is very useful in production of super LSI.
