PROBLEM TO BE SOLVED: To provide a light diffusion sheet useful as a light diffusion plate used for the panel or shade of a lighting apparatus, a signboard, an advertising lamp or the like and having high transmittance, high diffusivity, lightness, high strength and incombustibility. SOLUTION: A glass fiber reinforced fluororesin composite material obtained by pressing a fluororesin sheet having 2-500μm thickness and a glass fiber sheet having 2-10μm fiber diameter and 100-900 g/m2 coating weight at the melting point of the fluororesin or above is used as the light diffusion sheet disposed between a light source and a body to be illuminated. |
