Zusammenfassung:	To provide a silica aerogel having high transparency, excellent strength and high hydrophobicity, and a method for producing the silica aerogel.SOLUTION: The silica aerogel according to the present invention has a structure in which a skeleton having a fluorene moiety is bonded to a silicon atom. The method for producing the silica aerogel according to the present invention includes a step of subjecting a raw material containing a first hydrolyzable silane compound having the fluorene moiety and a second hydrolyzable silane compound other than the first hydrolyzable silane compound to a hydrolysis reaction.SELECTED DRAWING: None 【課題】透明性が高く、強度が優れる上に高い疎水性を有するシリカエアロゲル及びその製造方法を提供する。【解決手段】本発明のシリカエアロゲルは、フルオレン部位を有する骨格がケイ素原子に結合した構造を有する。本発明のシリカエアロゲルの製造方法は、フルオレン部位を有する第１の加水分解性シラン化合物と、該第１の加水分解性シラン化合物以外である第２の加水分解性シラン化合物とを含む原料を加水分解反応する工程を備える。【選択図】なし
