Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rubber composition having excellent transparency, a rubber molding obtained by using the rubber composition, and a method for producing rubber composition.SOLUTION: This invention relates to a rubber composition containing a rubber component and a filler. The filler contains silica particles, and an aggregation inhibitor that inhibits the agglomeration of the silica particles. The aggregation inhibitor contains at least one selected from the group consisting of a phosphate and a derivative thereof, an amino alcohol, a cationic surfactant, a water-soluble amino silane, a betaine compound, an alkylalkanolamine, a polyvinyl alcohol, a non-zinc soap and a saturated fatty acid ester.SELECTED DRAWING: None 【課題】透明性に優れるゴム組成物、そのゴム組成物を用いて得られるゴム成形品、および、ゴム組成物の製造方法を提供すること。【解決手段】ゴム成分とフィラーとを含有するゴム組成物において、フィラーが、シリカ粒子と、シリカ粒子の凝集を抑制する凝集抑制剤とを含有し、凝集抑制剤が、リン酸塩およびその誘導体、アミノアルコール、カチオン性界面活性剤、水溶性アミノシラン、ベタイン系化合物、アルキルアルカノールアミン、ポリビニルアルコール、非亜鉛せっけんおよび飽和脂肪酸エステルからなる群から選択される少なくとも１種を含有する。【選択図】なし
