The objective of the present invention is to provide an oil/fat composition for a solid roux, said composition making it possible to achieve the physical properties required of a solid roux, i.e. shape retention during summertime, resistance to seepage of a liquid oil component, resistance to surface whitening, and good melt-in-the mouth properties, as well as a reduction in trans-fatty acid and saturated fatty acid content. Provided is an oil/fat composition for a solid roux, said composition being characterized in that the composition has a triglyceride composition comprising 15-40 wt % of an S3 triglyceride, 10-30 wt % of an S2U triglyceride, 10-25 wt % of an SU2 triglyceride, and 30-50 wt % of a U3 triglyceride (S: a C16-24 saturated fatty acid, U: a C16-18 unsaturated fatty acid), the weight ratio between C16 (P: palmitic acid) and C18 (St: stearic acid) is 0.5≤;P/St≤;2.0, and SSU/SUS>;1.
