摘要：
An antibacterial composition having a heat-resistant property sufficient for avoiding its decomposition or discoloration at the resin molding temperature comprises; a silver thiosulfate complex salt carried on silica gel particles having an equilibrium water content of 10% or smaller, wherein at least part of the surface of the silica gel particles carrying said silver thiosulfate complex salt is covered with a coating layer composed of silicon dioxide formed by means of hydrolysis of an alkoxysilane.
