To provide a method for producing free monounsaturated fatty acid having 20 and/or 22 carbon atoms or lower alcohol ester thereof.SOLUTION: Provided is a method for producing free monounsaturated fatty acid having 20 and/or 22 carbon atoms or a lower alcohol ester thereof, including: subjecting a marine product raw material-derived oil/fat to hydrolysis or alcoholysis to obtain free fatty acid or lower alcohol ester; carrying out distillation for the free fatty acid or lower alcohol ester to reduce the concentration of a fatty acid having 18 or less carbon atoms in the free fatty acid or lower alcohol ester; and, by column chromatography using a reversed-phase distribution system, preparatively collecting fractions of free monounsaturated fatty acid having 20 and/or 22 carbon atoms or lower alcohol ester thereof.SELECTED DRAWING: None 【課題】炭素数２０及び／又は２２の遊離１価不飽和脂肪酸又はそれらの低級アルコールエステルを製造する方法の提供。【解決手段】水産物原料由来の油脂を加水分解又はアルコール分解して、遊離脂肪酸又は低級アルコールエステルを得ること、前記遊離脂肪酸又は低級アルコールエステルに対して蒸留を行い、当該遊離脂肪酸又は低級アルコールエステル中の炭素数１８以下の脂肪酸の濃度を低減させること、逆相分配系のカラムクロマトグラフィーにより、炭素数２０及び／又は２２の遊離１価不飽和脂肪酸又はそれらの低級アルコールエステルの画分を分取することを含む、炭素数２０及び／又は２２の遊離１価不飽和脂肪酸又はそれらの低級アルコールエステルを製造する方法。【選択図】なし
