<p>A transparent film has a high glass transition temperature, yet retaining high transparency. The transparent film includes a glass fiber substrate impregnated with a resin composition in which a high refractive resin having refractive index higher than the glass fiber is mixed with a low refractive resin having refractive index lower than the glass fiber to have resultant refractive index approximate to that of the glass fiber when cured. The high refractive resin includes a cyanate-ester resin so as to increase a glass transition temperature, yet retaining high transparency.</p>
