This resin composition comprises: a base resin containing an oligomer, a monomer, and a photopolymerization initiator; and inorganic oxide particles, wherein the inorganic oxide particles are massive agglomerated particles, and have a volume average particle diameter of 5-800 nm as measured through a small-angle X-ray scattering method. Cette composition de résine comprend : une résine de base contenant un oligomère, un monomère et un initiateur de photopolymérisation ; et des particules d'oxyde inorganique, les particules d'oxyde inorganique étant des particules agglomérées massives, et ayant un diamètre de particule moyen en volume de 5 à 800 nm tel que mesuré par l'intermédiaire d'un procédé de diffusion de rayons X à petit angle. 樹脂組成物は、オリゴマー、モノマー及び光重合開始剤を含有するベース樹脂と、無機酸化物粒子とを含み、無機酸化物粒子が塊状の凝集粒子であり、Ｘ線小角散乱法で測定される無機酸化物粒子の体積平均粒径が５ｎｍ以上８００ｎｍ以下である。
