Abstract
A curable composition capable of manufacturing a cured product having a high refractive index is provided. The curable composition contains a polymerizable compound represented by formula (1) and inorganic particles. In formula (1), La represents a divalent linking group, and the divalent linking group includes at least one of a divalent aromatic group, a divalent polycyclic aliphatic group and an alkylene group having an aromatic group, Ar represents an aromatic group, and R represents an aromatic group optionally having one or more substituents or a polycyclic aliphatic group optionally having one or more substituents.
