Disclosed is a fluidity improver for fats and oils, which is capable of sufficiently improving the fluidity of a fat or oil when the fat or oil is used as a fuel.nSpecifically disclosed is a fluidity improver for fats and oils, which is composed of a polymer that is configured of constituent units (I), (II) and (III) and has a weight average molecular weight of 5,000-100,000. The molar fraction (a) of the constituent unit (I) is 0.4-0.8; the molar fraction (b) of the constituent unit (II) is 0.1-0.3; and the molar fraction (c) of the constituent unit (III) is 0.1-0.3. |
