PROBLEM TO BE SOLVED: To provide a glass fiber film subjected to a transparent surface treatment having high transparency, high strength, excellent heat resistance, excellent electrical insulation properties, excellent dimensional stability, and excellent flexibility.SOLUTION: The transparent glass fiber film contains one surface-treated glass fiber film or a plurality of surface-treated glass fiber films which are layered and in the transparent glass fiber film, the surface-treated glass fiber film has a value of the commonly used flexural rigidity measured by a method described in JIS R 3420 which is three to one hundred times the value of the commonly used flexural rigidity of an untreated glass fiber film, and has a total light transmittance of 90% or more measured by a method described in JIS K 7375 at a wave length of 400-800 nm with a thickness of the film of 500 μm or less. |
