An object of the present invention is to provide a novel dextrin fatty acid ester which is excellent in tackiness and useful as a base material for cosmetics and the like. The novel dextrin fatty acid ester is an esterified product of dextrin and fatty acid, the average polymerization degree of glucose of dextrin is 3 to 150, and the fatty acid is one or more of branched saturated fatty acids having 4 to 26 carbon atoms More than 50 mol% and not more than 100 mol% and linear saturated fatty acid having 2 to 22 carbon atoms, linear or branched unsaturated fatty acid having 6 to 30 carbon atoms and cyclic saturated or having 6 to 30 carbon atoms 1 type or 2 types or more chosen from the group which consists of unsaturated fatty acids are contained 0 mol% or more and less than 50 mol% with respect to all the fatty acids, and the substitution degree of the fatty acid per glucose unit is 1.0-3.0.本発明は、タック性に優れ、化粧料などの基材として有用な新規なデキストリン脂肪酸エステルを提供することが課題である。新規なデキストリン脂肪酸エステルは、デキストリンと脂肪酸とのエステル化物であって、デキストリンのグルコースの平均重合度が３～１５０であり、脂肪酸が炭素数４～２６の分岐飽和脂肪酸の１種又は２種以上を全脂肪酸に対して５０ｍｏｌ％より多く１００ｍｏｌ％以下及び炭素数２～２２の直鎖飽和脂肪酸、炭素数６～３０の直鎖又は分岐の不飽和脂肪酸及び炭素数６～３０の環状の飽和又は不飽和脂肪酸よりなる群から選ばれる１種又は２種以上を全脂肪酸に対して０ｍｏｌ％以上５０ｍｏｌ％未満を含有し、グルコース単位当たりの脂肪酸の置換度が１．０～３．０である。
