Abstract
Provided are silicone particles having a rubber elasticity, a low cohesiveness, a high dispersibility in a resin, and alkenyl groups on the surfaces thereof; and a method for producing the same. The silicone particles are silicone elastomer spherical particles having surfaces thereof coated with polymethylalkenylsilsesquioxane, and having a volume average particle size of 0.1 to 100 μm, in which the polymethylalkenylsilsesquioxane is in an amount of 0.5 to 25 parts by mass per 100 parts by mass of the silicone elastomer spherical particles, and alkenylsilyl groups are present on the surface of the polymethylalkenylsilsesquioxane.
