To provide a fluorine grease composition with extremely less leaving and diffusion of a fluorine oil, i.e., a base oil from the inside of a grease component.

The fluorine grease contains a fluorine oil, as a base oil and a thickener such as polytetrafluoroethylene (PTFE), and contains 0.1-10 wt.% of silicone oil such as dimethylsilicone oil and 0.1-5.0 wt.% of nitrogen-containing surfactant such as an amine-based or amide-based surfactant. As the silicone oil, the silicone oil having kinematic viscosity at 40C of 1-500 mm2/s is preferable.
