Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a sheet in which folding whitening is improved, and a natural lighting property and incombustibility are possessed.SOLUTION: A natural lighting nonflammable sheet comprises glass fiber cloth embedded inside of a curable resin layer, and a thermoplastic resin layer laminated on at least one face of the curable resin layer through or not through an adhesive layer, and satisfies the following (a) and (b). (a): A mass ratio of a glass fiber composing the glass fiber cloth to a curable resin composing the curable resin layer is 20:80-70:30. (b): A folding time in which whitening generation by a folding examination by JIS P 8115 is at least 30 times. 【課題】折曲げ白化を改善した、採光性かつ不燃性を有するシートを提供する。【解決手段】硬化樹脂層の内部にガラス繊維布帛が埋設され、該硬化樹脂層の少なくとも一方の面に接着剤層を介してまたは介さずに熱可塑性樹脂層が積層されてなり、下記（ａ）及び（ｂ）を満足する採光不燃シート。（ａ）：ガラス繊維布帛を構成するガラス繊維と硬化樹脂層を構成する硬化樹脂との質量比が２０：８０〜７０：３０（ｂ）：ＪＩＳＰ８１１５の折り曲げ試験による白化発生が３０回以上の折り曲げ時【選択図】図１
