PROBLEM TO BE SOLVED: To provide a rolling oil composition that causes no surface damages even when exposed to rolling with a high reduction ratio and allows reduction in a rolling load. SOLUTION: The rolling oil composition for metal working comprises a base oil and, incorporated therewith, a sulfur-containing compound represented by general formula (I): R<SP>1</SP>OOC-R<SP>2</SP>-S<SB>x</SB>-R<SP>3</SP>-COOR<SP>4</SP>(I) (wherein R<SP>1</SP>and R<SP>4</SP>are each independently a 1C-20C hydrocarbon group; R<SP>2</SP>and R<SP>3</SP>are each independently a 0C-6C hydrocarbon group; and x is an integer of 1-3) in an amount of 0.01-70 mass% based on the whole composition.
