To provide a roll-in fat and oil composition containing milk fat, having a wide temperature range of plasticity so as to be excellent in extensibility in a low temperature, and scarcely being changed in hardness with time so as to be stable.

This roll-in fat and oil composition contains crystalline fat and oil of direct β type and the milk fat in its oil phase, wherein solid fat contents in the oil phase are 20-60% at a temperature of 10°C and 10-40% at a temperature of 20°C, respectively, and crystal form of the fat and oil in the oil phase is the direct β type of a two chain-length structure.
