To provide an organic-inorganic hybrid reaction product having high flexibility.SOLUTION: The organic-inorganic hybrid reaction product is produced by a condensation reaction of a composition containing: a dimethylpolysiloxane (A) having a hydroxy terminal; an aluminum alkoxide (B); and a silicon oligomer (C) in which an organic substituent is a methyl group. The composition preferably contains two or more kinds of the components (A) different in mass average molecular weight. The ratio NC/NA of the number NC of alkoxy groups of the component (C) to the number NA of hydroxy groups of the components (A) is preferably 0.10 or more and 5.15 or less.SELECTED DRAWING: None 【課題】柔軟性が高い有機無機ハイブリッド反応生成物を提供すること。【解決手段】有機無機ハイブリッド反応生成物は、ヒドロキシ末端を有するジメチルポリシロキサン（Ａ）と、アルミニウムアルコキシド（Ｂ）と、有機置換基がメチル基であるシリコンオリゴマー（Ｃ）とが含まれる組成物の縮合反応により生じたものである。前記組成物は、質量平均分子量が異なる２種類以上の前記（Ａ）成分を含むことが好ましい。前記（Ａ）成分が有するヒドロキシ基の数ＮＡと、前記（Ｃ）成分が有するアルコキシ基の数ＮＣとの比率であるＮＣ／ＮＡは、０．１０以上５．１５以下であることが好ましい。【選択図】なし
