Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat treatment oil composition having a high vapor film fracture effect upon heat treatment such as quenching for a metallic material, further capable of maintaining the vapor film fracture effect and also capable of imparting excellent brightness to a workpiece.SOLUTION: The heat treatment oil composition is obtained by blending (A) at least either one kind selected from hydroxy condensed fatty acid and a hydroxy condensed fatty acid derivative having a polymerization degree of 2 or more. Alternatively, the heat treatment oil composition is obtained by blending (B) at least either one kind selected from mineral oil and synthetic oil.
