To provide a photocurable material which can form a cured product having a high transparency and a high refractive index, a process for producing the material easily, and an article having a high transparency and a high refractive index. The photocurable material is obtained by a production process comprising (i) a step of reacting a polymerizable component (A) comprised of at least one type of a compound (a) having a (meth)acryloyloxy group, and a compound (B) having a mercapto group and a carboxy group to obtain a surface modifier (C) which has the carboxy group derived from the compound (B) at a terminal, (ii) a step of modifying the surface of inorganic fine particles (D) with the surface modifier (C) to obtain surface-modified inorganic fine particles (E), and (iii) a step of obtaining a photocurable material which contains the surface-modified inorganic fine particles (E), a polymerizable component (F) comprised of at least one type of a compound (f) having a (meth)acryloyloxy group, and a photopolymerization initiator (G).
