Zusammenfassung:	To easily deposit a coating liquid composition on a surface of a lens.SOLUTION: A production method of a hard coating liquid composition comprises following steps A to C: (step A) a step of dispersing a sol metal oxide or hydroxide in water to obtain an aqueous dispersion; (step B) a step of subjecting the aqueous dispersion obtained in step A and a silane coupling agent to hydrolysis and condensation reaction; and (step C) a step of adding a surface tension depressant and a penetrating and wetting agent to the product obtained in step B, and then agitating and aging the mixture.SELECTED DRAWING: None 【課題】コーティング液組成物をレンズの表面に容易に付着させること。【解決手段】以下の工程Ａ〜Ｃを含むことを特徴とする、ハードコーティング液組成物の製造方法。（工程Ａ）ゾル状金属酸化物又は水酸化物を水に分散させて水分散液を得る工程（工程Ｂ）工程Ａで得た水分散液を、シランカップリング剤と加水分解及び縮合反応させる工程（工程Ｃ）工程Ｂで得た生成物に、表面張力低下剤と浸透湿潤剤を加えた後、撹拌して熟成させる工程【選択図】なし
