PROBLEM TO BE SOLVED: To provide an oil and fat composition which contains diacylglycerol and wherein crystal deposition is suppressed, even at low temperatures.SOLUTION: A polyglycerine fatty acid ester wherein the mean degree of polymerization of the glycerine is ≥20 exhibits excellent inhibiting effect on diacylglycerol crystallization and improves low-temperature resistance. The oil and fat composition contains ≥20 mass% of components (A) and (B), with (A) being a polyglycerine fatty acid ester wherein the mean degree of polymerization of the glycerine is ≥20, and (B) being diacylglycerol. The content of an unsaturated fatty acid in fatty acids constituting the diacylglycerol is preferably 80-100% from the point of view of appearance and physiological effect.
