Summary:PROBLEM TO BE SOLVED: To provide a grease composition for electric contact capable of effectively reducing the abrasion of copper surface, copper alloy surface and noble metal surface(e.g. silver-plated surface, gold-plated surface) without causing chattering(voltage drop) even at a contact with fine current when used at low temperatures. SOLUTION: The grease composition for electric contact comprises a thickening agent, a base oil and an additive, wherein the additive comprises a quaternary ammonium salt of hectorite.
