PROBLEM TO BE SOLVED: To provide an antisticking agent composition for unvulcanized rubber, having good dryability, excellent in antistickingness than ever, and excellent in the slipperiness of unvulcanized rubber surface, and to provide a method for producing an unvulcanized rubber subjected to antisticking treatment by using the above composition. SOLUTION: The antisticking agent composition for unvulcanized rubber comprises an inorganic powder essentially consisting of a water-swelling clay mineral, a water-soluble polysaccharide and a surfactant. In this composition, based on 100 pts.wt. of the inorganic powder, the amounts of the water-soluble polysaccharide and the surfactant are 0.5-10 pts.wt. and 10-60 pts.wt. respectively, and the water-swelling clay mineral accounts for 30-80 wt.%.
