Disclosed is an electroconductive grease comprising a fluorine oil, an electroconductive material, and a thickening agent. In the electroconductive grease, 5 to 20% by weight of carbon black having a DBP oil absorption of not more than 250 ml/100 g is incorporated as the electroconductive material, and 2 to 15% by weight of fluorine-containing resin particles having an average primary particle diameter of not more than 1.0 μm are incorporated as the thickening agent. When the electroconductive grease comprises the carbon black having the specific properties and the fluorine-containing resin particles having the average primary particle diameter of not more than 1.0 μm, preferably PTFE particles, a high level of oil separation performance can be realized, that is, the degree of oil separation can be significantly reduced, and the degree can be lowered to not more than 10% by weight. |
