Oils and fats containing 10 to 80 mass % of 1,3-distearoyl-2-oleoylglycerol (SOS) and including a triple chain length β-type SOS crystal are provided. In the measurement of the X-ray diffraction of the triple chain length β-type SOS crystal, the diffraction peak A corresponding to spacing of 3.95 to 4.05 Å, the diffraction peak B corresponding to spacing of 3.80 to 3.95 Å, the diffraction peak C corresponding to spacing of 3.70 to 3.80 Å, and the diffraction peak D corresponding to spacing of 3.60 to 3.70 Å are observed. The ratio of the diffraction intensity of the diffraction peak C to the diffraction intensity of the diffraction peak D is 0.35 or less.
