Summary:To provide a silicone rubber member and micro-fluid device having hydrophilic property, and excellent transparency and bondability.SOLUTION: A silicone rubber member 20 consists of a silicone rubber composition having silicone rubber and carbinol-modified silicone oil, and at least part of surface of the member has a dry treatment surface 22 to which dry treatment is applied and which has hydrophilic property. The side chain type carbinol-modified silicone oil having carbinol group in a side chain of a straight-chain polymer is preferable as carbinol-modified silicone oil. A micro-fluid device 10 is equipped with the silicone rubber member 20.SELECTED DRAWING: Figure 2 【課題】 親水性を有し、透明性および接合性が良好なシリコーンゴム部材およびマイクロ流体デバイスを提供する。【解決手段】 シリコーンゴム部材20は、シリコーンゴムとカルビノール変性シリコーンオイルとを有するシリコーンゴム組成物からなり、表面の少なくとも一部に、乾式処理が施され親水性を有する乾式処理面22を有する。カルビノール変性シリコーンオイルとしては、直鎖状ポリマーの側鎖にカルビノール基を有する側鎖型カルビノール変性シリコーンオイルが好適である。マイクロ流体デバイス10は、シリコーンゴム部材20を備える。【選択図】 図2
