Zusammenfassung:	To provide a silicone particle having a heretofore unproposed shape and a method for producing the same.SOLUTION: A method for producing a silicone particle includes the steps of: subjecting a silane monomer having a polymerizable unsaturated group to hydrolysis and condensation in a solvent A including water, providing a dispersion liquid of a polysiloxane compound having a polymerizable unsaturated group; mixing the dispersion liquid with a solvent X that is not compatible with the solvent A and is not compatible with the polysiloxane compound; and subjecting the polysiloxane compound to radical polymerization.SELECTED DRAWING: Figure 1 【課題】従来提案されていなかった形状のシリコーン粒子及びその製造方法を提供する。【解決手段】本発明は、重合性不飽和基を有するシラン系単量体を、水を含む溶媒Ａ中で加水分解および縮合して重合性不飽和基を有するポリシロキサン系化合物の分散液を得る工程と、前記溶媒Ａと相溶せず、かつ前記ポリシロキサン系化合物とも相溶しない溶媒Ｘと、前記分散液とを混合する工程と、前記ポリシロキサン系化合物をラジカル重合する工程とを含むシリコーン粒子の製造方法である。【選択図】図１
