PROBLEM TO BE SOLVED: To provide a production method capable of simply producing a siloxane oligomer in a high yield when producing a siloxane oligomer by hydrolysis of a silicon halide compound and to provide a production method capable of selectively producing a linear or cyclic siloxane oligomer in particular.SOLUTION: The siloxane oligomer can be efficiently produced without performing any special agitation by providing two electrospray nozzles to oppose to each other in a medium liquid and in the medium liquid, electrostatically spraying in an electric field a first liquid sample containing a silicon halide compound from one nozzle and electrostatically spraying in an electric field a second liquid sample containing water from the other nozzle and allowing the liquid samples to collide and fuse with each other.SELECTED DRAWING: None 【課題】ハロゲン化ケイ素化合物の加水分解によりシロキサンオリゴマーを製造する場合において、簡便かつ高収率でシロキサンオリゴマーを生成させることができる製造法、特に鎖状や環状のシロキサンオリゴマーを選択的に生成させることができる製造法を提供する。【解決手段】２台のエレクトロスプレーノズルを媒体液体中で対向させ、媒体液体中で一方からハロゲン化ケイ素化合物を含有する第１液体試料を電場中に静電噴霧し、もう一方から水を含有する第２液体試料を電場中に静電噴霧し、衝突・融合させることにより、特別な撹拌を行うことなく効率よくシロキサンオリゴマーを製造することができる。【選択図】なし
