Abstract PROBLEM TO BE SOLVED: To provide a silicone hydrogel which has a high content of an acrylamide monomer and is transparent and excellent in balance between moisture content and wettability.SOLUTION: There is provided a silicone hydrogel which is obtained by polymerization of a polymerization stock solution containing a plurality kinds of monomers, where the polymerization stock solution contains 30 to 98 wt.% of at least one kind of silicone monomer based on the total amount of the monomer and the polymer component and contains 1 to 50 wt.% of one kind of non-silicone type (meth)acrylamide monomer having two or more hydroxyl groups in the molecule based on the total amount of the monomer and the polymer component. 【課題】 本発明は、アクリルアミドモノマー含有率が高く、かつ透明で含水率、濡れ性のバランスに優れたシリコーンハイドロゲルを提供することを目的とする。【解決手段】複数種のモノマーを含む重合原液を重合することにより得られるシリコーンハイドロゲルであって、該重合原液が、少なくとも1種類のシリコーンモノマーを、モノマー成分およびポリマー成分の合計量に対して30〜98重量%含み、かつ少なくとも1種類の、分子内に2つ以上の水酸基を有する非シリコーン系(メタ)アクリルアミドモノマーを、モノマー成分およびポリマー成分の合計量に対して1〜50重量%含むことを特徴とするシリコーンハイドロゲルとする。【選択図】なし
