PROBLEM TO BE SOLVED: To provide an oil and fat composition having a high oleic acid content, good oxidation stability and thermal stability, making meltability in the mouth, flavor and texture of the oil and fat composition and a food obtained by using the composition good, and not making the composition and the food greasy. SOLUTION: This oil and fat composition contains a transesterified oil and fat, and >=50 wt.% oleic acid. The transesterified oil and fat is obtained by subjecting (A) 99-40 wt.% oil and fat containing >=30 wt.% oleic acid, and (B) 1-60 wt.% extreme hardened oil obtained by hardening an oil and fat different from the oil and fat of the component (A), and containing >=60 wt.% stearic acid, to an ester-interchange reaction.
